Question

(81)^-1/4×4√81×(81)^0.2
simplify ​

Answer 1

$4( \sqrt{81} ) \times {81}^{ \frac{ - 1}{4} }$

$= {81}^{ \frac{1}{4} } \times \frac{1}{ {81}^{ \frac{1}{4} } }$

$here \: both \: \: the \: {81}^{ \frac{1}{4} } \: will \: be \: \\ cancelled \: \: so \: the \: remaining \: is 1$

$so \: answer \: is1$

Answer 2

$4( \sqrt{81} ) \times {81}^{ \frac{ - 1}{4} }$

= ${81}^{ \frac{1}{4} } \times \frac{1}{ {81}^{ \frac{1}{4} } }$

$\begin{lgathered}here \: both \: \: the \: {81}^{ \frac{1}{4} } \: will \: be \: \\ cancelled \: \: so \: the \: remaining \: is 1\end{lgathered}$

$so \: answer \: is$
