Answer:

-54.5%

Step-by-step explanation:

You will have to use this formula

$\frac{new value-oldvalue}{oldvalue}$

Simplify x^2(y^3)^4/xy^5=x^a•y^b

givi [52]

Answer: a = 1 b = 7

Step-by-step explanation:

x^2(y^3)^4/x.y^5 = x^a.y^b

x^2(y^12) = x^a.y^b

(x^2).(y^12)/x^y^5 = x.y^7

x.y^7= x^a . y^b -> x^1.y^7
