Find the Domain square root of x^16

$\sqrt{x^{16}}$

Step 1

Set the radicand in $\sqrt{x^{16}}$ greater than or equal to $0$ to find where the expression is defined.

$x^{16} \geq 0$

Step 2

Since the left side has an even power, it is always positive for all real numbers.

All real numbers

Step 3

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
