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
