Simplify, assume the variable represents a positive real number
kotykmax [81]

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

<h3>What is simplification?</h3>

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}}
