    divide 432 by 44

    is that \(\large\color{black}{ \displaystyle (44)^x=432 }\) or \(\large\color{black}{ \displaystyle (44)\times x=432 }\)

    and no the answer isn't a whole numb.

    the quickest step for (44)^x is take log base 44, and use a calculator for the left side. for (44) times x, just divide as welshfella has told you too

    u don't accept messages, so I will say this right here. you maid a mistake when you quoted the poster. The law of multiplying x^n times x^m gives x^(m+n)

    check your answer \[\huge\rm (4^4)^7 = 4^{32}\] is this right 4 times 7 =32? \[\large\rm (4^4)^8 =4^{32}\] both sides are equal ?? 4 times 8=32 ?? \[\huge\rm (4^4)^4 = 4^{32}\] 4 times 4 = 32 ?
