    this is pretty much impossible to read use the equation tool below and it will be clear

    lets work in side the parentheses first

    \[\frac{a^5}{a}=a^4\] right?

    and \[\frac{t^{-1}}{t^5}=\frac{1}{t^6}\] so we can go to \[\huge\left(\frac{9a^4}{t^6}\right)^2\]

    then multiply all exponents by 2, don't forget to square the 9 as well

    okay to make sure I'm following correctly... would I get \[\frac{ 18a ^{8} }{ t ^{12} }\]

    close, but you balked on squaring 9 you just doubled it

    is everything right except for the 18?

    yeah it should be \(81\)

    since \(9^2=81\) unless maybe you have a fit of dyslexia, then it could be \(18\)
