Answer:

A) 5 and B) 5

Step-by-step explanation:

A) 5x-12=13

+12 +12 (add 12 to the 13)

5x=25

(then divide 25 by 5 which is 5 so the answer is 5)

B) 8(x+3)=64 (first use distributive property)

8x+24=64

-24 -24 (then subtract 24 to 64 which is 40)

8x=40

(then divide 40 by 8 which is 5 so that is it!)

I believe this is correct, I hope this helps :D

$32^{- \frac{2}{5} } = ( \frac{1}{32}) ^{ \frac{2}{5} } = ( \frac{1}{32} )^{ \frac{1}{5} *2} = [ ( \frac{1}{32}) ^{ \frac{1}{5} } ]^{2} = ( \sqrt[5]{ \frac{1}{32} } ) ^{2} = ( \sqrt[5]{ \frac{1}{2}* \frac{1}{2} * \frac{1}{2} * \frac{1}{2} * \frac{1}{2} } )^{2}$ = $( \frac{1}{2} )^{2} answer$

the notebook
 $(32)^{- \frac{2}{5} } = ( \sqrt[5]{ \frac{1}{32} } )^{2} = ( \frac{1}{2} )^{2} = \frac{1}{4}$
