Question

How would you rewrite x^(9/7) ???

Answer 1

The given expression is

`x^(9/7)`

We can write it in radical form, and the denominator of the exponent became the power of the radical. That is

`x^(9/7) = \sqrt[7]{x^9}`

And

`\sqrt[7]{x^9} = \sqrt[7]{x^7*x^2}`

We can also write it as

`\sqrt[7]{x^7}*\sqrt[7]{x^2} = x \sqrt[7]{x^2}`

And that's the simplified form of the given exponential form .
