## Homework Statement

I have five questions on some review problems for our final I was given and I have forgotten how to do them. They are:

1) 3(sqrt(5-x)+1)-7=sqrt(5-x)+6

2) 2(64^x-2)=8(.25)^x+1

3) x-2-(4-x^2/x+2)=3x+7

4)-2A^-2+A^(-5/2)sqrtA+a^(-1/2)*a^(-3/2)

5)(3x^2y^7z^-2/12xy^8z^5)^2

## Homework Equations

None that I can think of

## The Attempt at a Solution

For #3 I have gotten it down to x=4x^2+15x+22, but this makes little sense and all of the other ones I have no clue on how to do them.

Thank you
