Question

Giúp hộ mình bài này nha !!!
Tìm x :

2⁵ . 3² - 8 . ( x - 2 ) = 2³

Answer 1

\(2^5.3^2-8\left(x-2\right)=2^3\)

\(32.9-8\left(x-2\right)=8\)

\(288-8\left(x-2\right)=8\)

\(8\left(x-2\right)=288-8\)

\(8\left(x-2\right)=280\)

\(x-2=280:8\)

\(x-2=35\)

\(x=35+2\)

\(x=37\)

Vậy ...

Answer 2

\(2^5.3^2-8.\left(x-2\right)=2^3\)

\(\Leftrightarrow\left(x-2\right)=2^5.3^2-8:2^3\)

\(\Leftrightarrow\left(x-2\right)=\left(32.9-8\right):2\))

=>x=35+2

=>x=37

Answer 3

sorry

<=>(x-2)=(32.9-8):8

Chổ này mới đúng nha bạn,thông cảm
