33. Simplify a^5/a^3
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]
47. Solve 1/2*[3/4divided by 1/2]
49. Solve sqrt of -100
a. sqrt of -100
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.
I'm not sure what you mean by the first one-33
I mean: sqrt a^2= a by definition.
sqrt 16 = 4
