3. WEEK3LESSONOBJECTIVES
1. Describes principal roots and tells whether
they are rational or irrational.
2. Determines between what two integers the
square root of a number is
3. Estimates the square root of a whole
number to the nearest hundredth
4. Plot irrational numbers (up to square roots)
on a number line

4. SQUAREROOT
A square root of a number is a
number when multiplied to itself
will give you the original number.
Example, the square root of 9 are +3 and -
3 because when +3 and -3 are multiplied to
themselves, they are equal to 9.
If the square root of a number is
nonterminating, non-repeating decimal, we say
that it is an irrational number.

5. Every positive number has two square roots,
one is positive and the other is negative. The
principal square root is the positive square root
of the given number or radicand.
The principal root is rational if the radicand
is a perfect square.
Zero has only one square root, which is zero.
Negative numbers do not have real square
roots. Their square roots are called imaginary
numbers, which are tackled in a higher branch
of Mathematics.
