Exponent
Exponents indicate how many times a number, known as the base, is used as a factor in a multiplication. The exponent is written as a small number to the right and above the base number. Examples show that 82 means 8 multiplied by itself 2 times and 53 means 5 multiplied by itself 3 times, with the exponent indicating the number of times the base is used as a factor.

The document outlines steps for working with fractions including: changing improper fractions to mixed numbers and vice versa; reducing fractions; raising fractions to higher terms; finding the part of one number that is another number; and comparing fractions. Key steps are to divide the numerator by the denominator to change an improper fraction to a mixed number, multiply the whole number by the denominator and add the numerator to change a mixed number to an improper fraction, and find a common denominator to compare fractions.
Fractions
A fraction represents a part of a whole or group. It consists of a numerator above a fraction bar and a denominator below. The numerator indicates the number of parts being considered and the denominator indicates the total number of parts. A proper fraction has a numerator less than the denominator, while an improper fraction has a numerator greater than or equal to the denominator. A mixed number is a whole number plus a proper fraction. Fractions can be represented on a number line and equivalent fractions have the same value, even if their numerators and denominators are different.

Fractions represent parts of a whole and have two parts - a numerator and denominator. The numerator is the number on top and represents the parts, while the denominator is on the bottom and represents the total parts of the whole. There are three types of fractions: proper fractions where the numerator is less than the denominator, improper fractions where the numerator is greater than the denominator, and mixed fractions which are an improper fraction combined with a whole number.

Laws Of Exponents
This document introduces the laws of exponents. It defines key terms like exponent, base, and power. It then outlines six laws of exponents: 1) the product law, 2) the quotient law, 3) the power law, 4) powers with different bases, 5) zero exponents, and 6) negative exponents. It concludes by explaining how to simplify powers and exponential expressions by applying these laws and definitions of exponents.

Powers raise a number or symbol to an exponent by multiplying it by itself. Negative powers produce fractions. The product, power, and quotient rules describe how to manipulate exponents when multiplying, raising to a power, or dividing terms with the same base. A root extracts a root of a number by raising it to a fractional exponent. Common and natural logarithms are two types that describe the power to which bases of 10 or e must be raised to obtain a given number. Logarithm rules allow logarithms of multiplied, divided, or raised terms to be expressed in terms of the logarithms of their components.
