This is a pure base knowledge question. In other words, you have to know the rules of exponents. We have to find the answer where the lHS = RHS
A. \((x^n)^{\frac{1}{m}}= x^{\frac{n}{m}}\) which is equal to the LHS. So this is true
B. \(x^{a^b} \neq x^{ab}\) So this is not true
C. \(a^{a+a+a...times}= x^{a^2}\) So this is true
D. essentially in numbers this option is similar to A. So this is false
E. same as D
A and C are the only correct answer choices
