Square Roots and Cube Roots

Remember that when multiplying decimals we add the decimal places

so 0.3 x 0.3 would result in 2 decimal places

What number that is a perfect square do you see?

49!

we know square root of 49 = 7

Now we have to split 4 zeros between 2 numbers so each number gets 2eros

so 700

Remember to do the square root before you do the multplication! #PEMDAS

Simplify under the radical first!

since both numbers under the radical are not perfect squares, simplify the fraction then try to find the perfect squares

If it is an even exponent. A negative number in parenthesis will be positive

No Parenthesis = ALWAYS NEGATIVE
