If a^1/n=r then which of the following statements are true check all that apply a. r^n=a b. n^1/r=a c.^n√a=r d. a^r=n

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.

the correct answer is 1.7
