Please simplify this rational expression
x^26x27 multiplied by x^2 +8x+16 over x^218x81 multiplied by x^2+ 7x+12

algebra 
Reiny,
(x^26x27 )(x^2+8x+16)/(x^218x81) (x^2+7x+12)
= (x9)(x+3)(x+4)(x+4)/((x9)(x9)) (x+3)(x+4)
= (x+3)^2 (x+4)^3 / (x9)
did you mean at the end ....
over (x^218x81 multiplied by x^2+ 7x+12) ?
