    Answer:

    18√7x⁶

    Step-by-step explanation:

    Given the expression 7√28x⁶+4√7x⁶, we are to fund the sum in its simplest form as shown;

    7√28x⁶+4√7x⁶

    = 7√(7*4)x⁶+4√7x⁶

    = 7*2√7x⁶+4√7x⁶

    = 14√7x⁶+4√7x⁶

    Factor out the like term

    = 2√7x⁶(7+2)

    = 2√7x⁶(9)

    = 18√7x⁶

    Hence the sum is equivalent to 18√7x⁶
