Question

Simplify: [(6x^3 y^-4)^-2] / [(3x^2 y^5)^-3] (The / is the fraction line)

A) 3y^23 / 4

B) 6y^-24 / 4

C) 2y^-7 / x

D) 2x^-2 / y^-3

Answer 1

Opening the brackets, we have:
6^-2 x^-6 y^8
__________
3^-3x^-6 y^-15

= -36 x^-6 y^ 8
__________
-27 x^-6 y^-15
=
27 x^6 y ^15
_________
36 x^6 y^-8

divide the coefficients by 9. Work out the variables.

= 3y^23
_____
4
