Question

[Alisia]

giúp mk nhé

\(\dfrac{\left(-5\right)^3.40.4^3}{135.\left(-2\right)^{14}.\left(100\right)^0}\)

Answer 1

[Nguyên]

\(\dfrac{\left(-5\right)^3.40.4^3}{135.\left(-2\right)^{14}.\left(100\right)^0}=\dfrac{\left(-5\right)^3.2^3.5.2^6}{3^2.5.2^{14}}\)

* giải thích : \(100^0\)= 1 nên mik ko viết nữa

\(\left(-2\right)^{14}=\left(2\right)^{14}\)

ta có : \(\dfrac{\left(-5\right)^3.2^9.5}{3^2.2^{14}.5}=\dfrac{-125}{9.32}=\dfrac{-125}{288}\)

tik mik nhé
