Which of the following is the radical expression of 2 times d to the seven tenths power?

seventh root of 2 d to the tenth power

tenth root of 2 d to the seventh power

2 times the tenth root of d to the seventh power

2 times the seventh root of d to the tenth power

2 time the tenth root of d to the seventh power
When powers are in fractions, the denominator is a root and the numerator is a power. "2 times" means that two will be multiplied to d after its exponents are solved; otherwise the statement would've been "the product of 2 and d to the seven tenths power."
