I am not understanding these kinds of problems: I cannot simplify with understanding.
7 times the 4th root of m^3 plus 9 times the 4th root of 256m^3.

it can also be written as:
7 x [m^(3/4)] + 9[256m^(3/4)]
solve it

a correction is in order, as it should be
7 x [m^(3/4)] + 9[(256m^3)^(1/4)]
= 7∜m^3 + 9(∜256∜m^3)
= 7∜m^3 + 9(4∜m^3)
= 43∜m^3
