33. Simplify a^5/a^3
a^2?
Because I think when it's like that you subtract the two powers.
Simplify sqrt of a^2
How do you do this?
44. Solve 1/2 * [3/4 + 1/2]
1/2*5/4
5/8?
47. Solve 1/2*[3/4divided by 1/2]
3/4?
49. Solve sqrt of 100
a. sqrt of 100
b. 10
c. 10
d. No answer
C? I think C because I don't think there can be a negative inside a square root, but I'm not sure

MC; sqrt of a^2 is a, by definition.
49. THe correct answer is 10sqrt(1), or as some write it, 10i
a. is the best choice, but dumb.
47. yes.
44. yes 
I'm not sure what you mean by the first one33

I mean: sqrt a^2= a by definition.
sqrt 16 = 4
