Question

Tính

\(\left(\frac{-10}{5}\right)^5.\left(\frac{-6}{5}\right)^4\)

Answer 1

(\(\frac{-10}{5}^5\)) .(\(\frac{-6^4}{5}\))= \(\frac{-10^4}{5}\) . \(\frac{-6^4}{5}\) . \(\frac{-10}{5}\) =( \(\frac{-10^4}{5}\).\(\frac{-6^4}{5}\)).\(\frac{-10}{5}\)= \(\frac{60^4}{5}\).-2=\(\frac{60^4.-2}{5}\)

Answer 2

\(\left(\frac{-10}{5}\right)^5.\left(\frac{-6}{5}\right)^4=\left(\frac{-10}{5}\right)^4.\left(\frac{-6}{5}\right)^4.\left(\frac{-10}{5}\right)=\left[\left(\frac{-10}{5}\right).\left(\frac{-6}{5}\right)\right]^4.\left(-2\right)=\left(\frac{60}{5}\right)^4.\left(-2\right)=12^4.\left(-2\right)\)
