Simplify, assume the variable represents a positive real number

The simplification of the given expression [tex]\sqrt{18y^{21}[/tex] will be equal to [tex]3\sqrt{2} (y)^{\dfrac{21}{2}}[/tex]
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:
[tex]=\sqrt{18y^{21}}\\\\\\=(18)^{\frac{1}{2} } \times (y)^{\frac{21}{2}}\\\\\\=3\sqrt{2}\times y^{\frac{21}{2}}[/tex]
hence the simplification of the given expression [tex]\sqrt{18y^{21}[/tex] will be equal to [tex]3\sqrt{2} (y)^{\dfrac{21}{2}}[/tex]
