Answer 1

Hello! : )

The correct answer to your question is... $2^{3} y^{5}$

Evidence:
Step 1:     Simplify $y^{2}$/5

( 40 multiplied by $y^{2}$/5 multiplied by $y^{3}$ )


Step 2:     $y^{2}$ multiplied by $^{3}$ = y(2 + 3) = $y^{5}$


So the correct answer is... $2^{3} y^{5}$

I hope this helped! : )

Answer 2

Ok so 40y2/50y3.... you are going to cancel out the common factor (10)  
 
4y2/5y3..
now apply the exponent rule, which is : xa /xb = 1/ xb-a

so...y2/y3 = 1/ y3 - 2 = 1/y

ANSWER : 4/5y
