Question 791084: What is the simplified expression of
I got 2k/m^2 in order to answer with positive exponents Found 2 solutions by Edwin McCravy, rothauserc:Answer by Edwin McCravy(20062) (Show Source):
Write 8 as 23
To remove the parentheses, multiply each exponent
inside the parentheses by the exponent just above
outside the parentheses on the right:
So multiply both both 3 exponents and the -6 exponent
which are inside the parentheses by the exponent
outside the parentheses. You get:
Next use the rule that a negative exponent can be moved
form numerator to denominator or denominator to
numerator by changing the sign of the exponent to
positive:
And of course you can erase the 1 exponents:
, looks like you're exactly right!

You can put this solution on YOUR website! when an algebraic expression is raised to an exponent, we multiply each element of the algebraic expression by that exponent, and we get
(8)^1/3 *k *(m)-2
now we can simplify this expression
2k / m^2
