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

49. THe correct answer is 10sqrt(-1), or as some write it, 10i

a. is the best choice, but dumb.
