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 .
