Need help with Rational Exponents
We had the following problem: the 6th root of 125a to the 3rd power times b to the 9th power times c to the 6th power. I was able to get this to 125 to the 1 over 6th power times bc times the square root of ab. I need help understanding how the answer is bc times the square root of 5ab.

Re: Need help with Rational Exponents
Why did the vector cross the road?
It wanted to be normal.
