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.

  • Algebra -

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

    solve it

  • Algebra -

    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
