Question

Consider the equation: 625(5xy)^-3/(5x)^2 y^7
The equivalent simplified form of this expression is
A. 1/[5x(y^5)]
B. 1/[25(X^5)(y^10]
C. 1/[5(x^5)(y^10)]
D. 5(x^-1)(y^-4)

Answer 1

(5xy)^-3 is the same as 1/(5xy)^3

Answer 2

so move that value to the denominator

Answer 3

now we are left with
625/((5xy)^3(5x)^2y^7)

Answer 4

can you simplify that?

Answer 5

not sure i'll try

Answer 6

625/(3125x^5y^10)

Answer 7

one last simplification gives
1/[5(x^5)(y^10)]
