Square Roots PPT only for student easy to make.mayank887aa
It is the best PPT for square root.
For any class. It is made on PowerPoint and is easy to make. In mathematics, we might have encountered different numbers such as even, odd, prime, composite, etc. However, there is a particular type of number, i.e. a perfect square. These can be identified and expressed with the help of factorization of a number. In this article, you will learn the definition of perfect square numbers, notation, the list of these numbers between 1 and 100, and so on. We know that the square of a number is that number times itself. In other words, the perfect squares are the squares of the whole numbers such as 1 or 12, 4 or 22, 9 or 32, 16 or 42, 25 or 52, and so on.
Perfect Squares Definition
An integer that can be expressed as the square of another integer is called a perfect square. In other words, it is defined as the product of some integer with itself. Perfect square numbers are not only limited to numerals but also exist in algebraic identities and polynomials. These can be identified with the help of a factorization technique. There are eight perfect squares between 1 and 100 (i.e., excluding 1 and 100).
They are 4, 9, 16, 25, 36, 49, 64 and 81.
However, there are ten perfect squares from 1 to 10. They are 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100. There are 30 perfect squares between 1 and 1000. They are 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289, 324, 361, 400, 441, 484, 529, 576, 625, 676, 729, 784, 841, 900 and 961.
Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”

Problem of the Day
A Shakespearean sonnet is a poem
made up of 3 quatrains (4 lines each),
and a couplet (2 lines). Each line is in
iambic pentameter (which means it has
5 iambic feet). So, how many iambic
feet long is a Shakespearean sonnet?

4-5 Squares and Square Roots
Think about the relationship between the area
of a square and the length of one of its sides.
Taking the square root of a number is the
inverse of squaring the number.
Every positive number has two square roots, one
positive and one negative. One square root of 16 is 4,
since 4 • 4 = 16. The other square root of 16 is –4,
since (–4) • (–4) is also 16. You can write the square
roots of 16 as ±4, meaning “plus or minus” 4.
area = 36 square units
side length = 36 = 6 units
62 = 36 36 = 6

called the principal square root of the number.
