Question

X^9/7 convert from exponent form to radical form

Answer 1

Answer:

$x^{\frac{9}{7}} = \sqrt[7]{x^9}$

Step-by-step explanation:

You can solve this by realising that the denominator of a fractional exponent can be expressed as the base of a radical.

Note also that the order does not matter.  You could also express it as

$\sqrt[7]{x}^9$

The reason this works is that you're effectively breaking the exponent into fractions.  The first answer is the equivalent of:

$(x^9)^{1/7}$

and the second would be:

$(x^{1/7})^9$

In both cases, the exponents would be multiplied, giving the same result.
