Question

Simplify
7^2x^-3y/49x^-3y^-2

Answer 1

This is the answer I got
x(xy-7)^2

Answer 2

`(7^2x^(-3))/(49x^(-3) y^(-2)) \\ \\ (49x^(-3)y)/(49x^(-3)y^(-2)) \\ \\ (49x^(-3)y)/(49x^(-3) * (1)/(y^2) ) \\ \\ (49x^(-3)y)/( (49x^(-3))/(y^2) ) \\ \\ 49x^(-3) y * (y^2)/(49x^(-3)) \\ \\ (x^(-3))/(x^(-3)) yy^2 \\ \\ 1 * yy^2 \\ \\ yy^2 \\ \\ y^3 \\ \\`

The answer is: y^3.
