I have the following:

How do you go about simplifying this? DO you simplify each part individually by the 1/2 exponent? Thank you for any tips.

you can't do it individually because it is the same as:

to do this you have to subtract .can you do that? - August 14th 2011, 04:52 PMYoungMarbleGiantRe: Simplifying This Expression

As you were told above, the square root of a sum/difference is NOT equal to the sum/difference of the square roots. So you can't take each term in the numerator to the 1/2 power.

However, the square root of a product/quotient DOES equal the product/quotient of the square roots. So you CAN take the square root of the numerator and the square root of the denominator. - August 14th 2011, 06:42 PMYoungMarbleGiantRe: Simplifying This Expression
