Question

Simplify, assume the variable represents a positive real number

Answer 1

The simplification of the given expression $\sqrt{18y^{21}$ will be equal to $3\sqrt{2} (y)^{\dfrac{21}{2}}$

What is simplification?

The process of reducing the complex mathematical expressions into the simplest form is called as the simplification.

The simplification of the given expression will be:

$=\sqrt{18y^{21}}\\\\\\=(18)^{\frac{1}{2} } \times (y)^{\frac{21}{2}}\\\\\\=3\sqrt{2}\times y^{\frac{21}{2}}$

hence  the simplification of the given expression $\sqrt{18y^{21}$ will be equal to $3\sqrt{2} (y)^{\dfrac{21}{2}}$
