Homework Help: Calculus

State whether the following are true or false.

The square roots of 36 are + and - 6. I wrote down false for this cause I thought it was only + 6, but the real answer is true, and I want to know that how can it be negative?

Also for this:

Convert the following radicals to mixed radicals in simplest form.

I did this without making the factor tree, my teacher showed me an easy way.

ã50 = ã2*5*5 = 5*5ã2 = 25ã2
That's what I got 25ã2, but the answer is supposed to be 5ã2. I don't understand, did they reduce or something?
