Mi aiutate...per favore

=2^4·(-3)^6/((-3)^6·((-3)^2 + 2·(-3) + 5))=

=2^4/((-3)^2 + 2·(-3) + 5)=

=16/(9 + (-6) + 5) = 16/8= 2

-------------------------------------------------------------------

$\frac{[(-2)^2(-3)^3]^2}{[(-3)^8+2(-3)^7+5(-3)^6]}$ =

= $\frac{[4(-27)]^2}{6561+(-4374)+3645}$ =

= $\frac{[-108]^2}{6561-4374+3645}$ =

= $\frac{11664}{5832}=2$
