Question

If r^n=a, then which of the following are true statements? Check all that apply.

a. a^1/n=r b. a^r=n c. n sq a =r d. n^1/r=a

Answer 1

a. This is correct. When you transfer n to the other side, that would be the reciprocal power of a.

b. This is incorrect, because this contradicts with choice a.

c. This is correct. When a number is raised to a "1/n" fraction, that is equivalent to the nth root of the number.

d. This is incorrect, because it is not equivalent to the given equation.

Thus, the answers are A and C.
