4. Ex 1-2 Simplify 1) 2) If there are two Of a kind Bring it Out front as One number

5. Ex 3 Simplify 3) If there are two Of a kind Bring it Out front as One number Sq root of 9 Is 3

6. Ex 4 Simplify (short cut) 4) Square root of 16 is 4 Divide index (2) into exponents On variables. Leave left overs Under radical. 9/2 = 4 with 1 left over 6/2 = 3

7. Ex 5 Simplify (short cut) 5) Square root of 25 is 5 Divide index (2) into exponents On variables. Leave left overs Under radical. 11/2 = 5 with 1 left over 23/2 = 11 with 1 left over

8. Ex 8-9 Simplify 8) 9) If there are two Of a kind Bring it Out front as One number
