Question 202049
{{{(27a^8)/(9a^4)-(78a^9)/(3a^5)}}} Start with the given expression.



{{{(3a^8)/(a^4)-(26a^9)/(a^5)}}} Reduce the coefficients.



{{{3a^(8-4)-26a^(9-5)}}} Divide the variable terms by subtracting the exponents.



{{{3a^4-26a^4}}} Subtract



{{{-23a^4}}} Combine like terms.



So {{{(27a^8)/(9a^4)-(78a^9)/(3a^5)=-23a^4}}} where {{{a<>0}}}
