5^4 the square root of 32 - the 4th square root 162
\(\color{#000000}{ \displaystyle 5\sqrt[4]{32}-\sqrt[4]{162} }\) ?
like that?
\[5\sqrt[4]{32} - \sqrt[4]{162}\]
Hint: \(\color{#000000}{ \displaystyle 162=2\cdot 3^4 }\)
Also, \(\color{#000000}{ \displaystyle 32=2^5=2\cdot 2^4 }\)
So, you can brake this the following way. \(\color{#000000}{ \displaystyle 5\sqrt[4]{32}-\sqrt[4]{162} }\) \(\color{#000000}{ \displaystyle 5\sqrt[4]{2\times 2^4}-\sqrt[4]{2\times 3^4} }\) \(\color{#000000}{ \displaystyle \{5\sqrt[4]{2}\times 5\sqrt[4]{ 2^4}\}-\{\sqrt[4]{2}\times \sqrt[4]{ 3^4} \} }\)
Note that \(\color{#000000}{ \displaystyle \sqrt[4]{2^4}=2 }\) and \(\color{#000000}{ \displaystyle \sqrt[4]{3^4}=3 }\).
and then all there will be left is to add like terms.
this does not make any sense
oh well
look you don't have to get smart with me...
