Question

Which of the following is the radical expression 2d 7/10

Answer 1

`2d^{(7)/(10)}`
`= \sqrt[10]{2d^7}`

Explanation:

Given

`2d^{(7)/(10)}`

Required

Determine the radical expression

To do this, we apply the following law of indices:

`a^{(m)/(n)} = \sqrt[n]{a^m}`

By comparing the above to
`2d^{(7)/(10)}`, we have:

`m=7`

`n = 10`

So, the solution becomes

`2d^{(7)/(10)}`
`= \sqrt[10]{2d^7}`
