    Please use the Equation editor, the problem is not clear. Does it look like this? \[(3x * y^4) 2 (y^2)^3\]

    apply the exponent rules \[\huge\rm (x^m)^n=x^{m \times n}\]

    and \[\huge\rm (ab)^x =a^x b^x\]

    \[\huge\rm (ab c^m)^x =a^x b^x c^{m \times x}\] (3xy^4)^2 should be like this

    2 is an exponent of all numbers and variables in the parentheses (3xy^4)^2 = ?

    (3xy^4)^2=a^2b^2c^4*2

    hmm welll that was an example now here a=3 b=x c=y so \[3^2 x^2y^{4 \times 2}\]

    \[\huge\rm (3)^2x^2y^{4 \times 2}(y^2)^3\] (y^2)^3 is same as y^{2 times 4}
