Which of the following is the simplified form of fifth root of x times the fifth root of x times the fifth root of x times the fifth root of x? a) x to the 1 over fifth power

b) x to the 4 over fifth power

c) x to the 4 over twentieth power

d) x

The mathematically expression of the given above is,

(x^1/5) (x^1/5) (x^1/5) (x^1/5)

For the same variable involved in the operation multiplication, the exponents should be added. Thus, the answer is,

x^4/5

or x to the 4 over fifth power. The answer is letter B.
