Solving Radical Expressions.

MONSTER QUESTION. ahhh.
okay.
When i first looked at this question I was so confused and I didn't know where to start.
So I remembered what Mr.Cheng says about taking it one step at a time.
and start with little and work your way up. This is what I did
1. The first thing I did was get rid of the negatives. You do this by flipping them.
2. You distribute the exponent outside of the brackets
3. You are left with a fraction exponent so you distribute those too on the numbers.
4. Then you distribute the fraction exponent of the variables and turn the squares and exponents of the numbers into a number.
5.The square roots of the variables cancelled each other out and the exponent can both be divided by 2.
and then you have your answer.
YAY. not so hard.
