# Which of the following expressions is equal to root19d?

$\sqrt[19]{d} = {d}^{\frac{1}{19}}$

#### Explanation:

I don't see any options here, but in general we can write a root using fractional exponential notation. So for instance, I can write:

$\sqrt{d} = {d}^{\frac{1}{2}}$

and so I can write $\sqrt[19]{d} = {d}^{\frac{1}{19}}$

Hopefully that is one of the options you were looking for.
