Use the properties of exponents to simplify each of the following expressions, writing your answer with only positive exponents.
\[\left[ 5m^4n^{-2})^{-1} \right]^{-2}\]
(m^8)/(25n^4)
How did you solve it Meverett04? Can you show me the steps please?
\[(x^m)^n = x^{mn}\] and \[x^{-m} = \frac{1}{x^m}\] is what you need here
For m, multiply the exponents 4 times -1 times -2 equals 8
For n, multiply the exponents -2 times -1 times -2 equals -4 but since we have a negative four, this will go in the denominator with a positive 4
For 5 5^2 or five squared is 25, but since we have a negative exponent, we place the 25 in the denominator
thanks man!
here is another problem if you would like to help me solve it.
\[\left[ 100^0(x^{-1}y^3)^{-1}/x^2y \right]^{-3}\]
I didn't know how to post it as a fraction but if i did x^2y would be the denominator.
