Using Radicals with Elementary Operations - Math

Exponents in the denominator can be subtracted from exponents in the numerator.

Recall that .

Therefore, .

When combining terms involving radicals, we can only combine the ones that have the same radical. For this problem, that means has to stay on its own while we can combine and into . The simple integers can be combined too, giving us our answer with three seperate terms.

Try to group factors in pairs to get perfect squares under the square root:

Exponents in the denominator can be subtracted from exponents in the numerator.

Recall that .

Therefore, .
