Question

Simplify (2x)^3 x (3y)^5

Answer 1

wait its actually (2x)^-3

Answer 2

\[(2x)^{-3}\times(3y)^5\]
\[2^{-3}x^{-3}\times3^5y^5\]

Answer 3

From there...

Answer 4

\[1/(2^3x^3) \times243y^5\]

Answer 5

\[243y^5/(8x^3)\]

Answer 6

So at this point, you have no more negative exponents, none of the numbers simplify, and the variables can't be combined or simplify either. This is how you can tell you are finished. :)
