Sagot :

Explanation

We can add or subtract radical expressions only when they have the same radicand(the number found inside a radical symbol) and when they have the same radical type such as square roots. However, it is often possible to simplify radical expressions, and that may change the radicand.

so

[tex]\sqrt[n]{a^m\text{ }}^{}+\text{ }\sqrt[n]{b^m}[/tex]

so, in this case the expression can not be simplied more
