=(-378000)/84000

=-9/2

\(A=\frac{\left(-2\right)^3.3^3.5^3.7.8}{3.2^4.5^3.14}=\frac{\left(-8\right).3^2.3.5^3.7.8}{3.2^3.2.5^3.2.7}=\frac{\left(-8\right).9}{2.2}=\frac{-72}{4}=-18\)

C.ơn bạn nhiều nha ... nha ... nha

\(\frac{\left(-2\right)^3.3^3.5^3.7.8}{3.2^4.5^3.14}=\frac{\left(-2\right)^3.3^3.5^3.7.2^3}{3.2^4.5^3.2.7}=\)\(\frac{\left(-2\right)^6.3^3.5^3.7}{3.2^5.5^3.7}=\frac{-2.3^2}{1}=-18\)

~~~ học tốt ~~~

Chúc bn hok tốt!

Giải chi tiết nha m.n

\(\frac{\left(-2\right)^3.3^3.5^3.7.8}{3.2^4.5^3.14}=\frac{2^5.3^3.5^3.7.\left(-2\right)}{3.2^5.5^3.7}=\frac{3^2.\left(-2\right)}{1}=-18\)

Ta có: \(\frac{\left(-2\right)^3.3^3.5^3.7.8}{3.2^4.5^3.14}=\frac{\left(-2\right)^3.3.3^2.5^3.7.2^3}{3.2.2^3.5^3.2.7}=\frac{-\left(2\right)^6.3^2}{2^2}=\frac{\left(-64\right).9}{4}=-\frac{576}{4}\) \(=-144\)

= - 144 nha♡♡♡
