Question

$\frac{3 {}^{3} \times3 {}^{ - 4} {} }{3 {}^{ -5} \times3 {}^{6} }$
como resolvo esse calculo, please me ajudem​

Answer 1

$\frac{3^3~.~3^{-4}}{3^{-5}~.~3^6}~=~\frac{3^{\,3+(-4)}}{3^{3^{\,-5+6}}}~=~\frac{3^{-1}}{3^1}~=~3^{\,-1-1~}~=~3^{-2}~=~\left(\frac{1}{3}\right)^2~=~\frac{1^2}{3^2}~=~\boxed{\frac{1}{9}}$
