Which of the following is not true? A) x^-7 = 1 / x^7

Question

Which of the following is not true?

A) x^-7 = \(\frac{1}{x^7}\)

B) x⁵ = \(\frac{1}{x^-5}\)

C) x° = 1 

D) \(\frac{1}{x^-5}\) = x^1/5

Answer 1

Correct option is D) \(\frac{1}{x^-5}\) = x^1/5

^{\(\frac1{x^{-5}}=(x^{-5})^{-1}\)} = x⁵ \(\neq\) x^1/5

Answer 2

correct answer is D 

because 

1/x^-5= x^5
