Answer 2

The fractional index form of $\sqrt{15}$ is $15^{\frac{1}{2} }$.

Step-by-step explanation:

Given,

$\sqrt{15}$

We have to a fractional index to write $\sqrt{15}$

nth root of a can be written as

$\sqrt[n]{a}$  or  $a^{\frac{1}{n} }$

$a^{\frac{1}{n} }$ a is base and $\frac{1}{n}$ is the index

Square root of a can be written as

$\sqrt{a}$   or   $\sqrt[2]{a}$  or   $a^{\frac{1}{2} }$

Given is $\sqrt{15}$  which is equivalent to $\sqrt[2]{15}$ .

So, the fractional index form of $\sqrt{15}$ is $15^{\frac{1}{2} }$.
