    put that where the quotient goes and then multiply by the divisor to figure out what you need to subtract

    so we have (8n-27)-(8n-32) which is ...

    so we aren't dividing. I would say it is already simplified

    and i said it wrong the funtion is actually\[\sqrt{(8^{n}-27)\div (4^{-n})}\]

    =\[\sqrt{8^n*4^n-27(4^n)}=\sqrt{32^n-27(4^n)}\]

    \[\sqrt{4^n}*\sqrt{(8^n-27})=2^n*\sqrt{(8^n-27)} \]
