a) -45 : ( 3x - 17 ) = 32
3x - 17 = -45 : 9
3x - 17 = -5
3x = 12
x = 4
b) \(\left(2x-8\right)\left(-2x\right)=0\)
\(\Rightarrow\orbr{\begin{cases}2x-8=0\\-2x=0\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}x=4\\x=0\end{cases}}\)
Vậy.....
c) \(72:\left|4x-3\right|=2^3\)
\(\left|4x-3\right|=9\)
\(\Rightarrow\orbr{\begin{cases}4x-3=9\\4x-3=-9\end{cases}}\)
\(\Rightarrow\orbr{\begin{cases}x=3\\x=\frac{-3}{2}\end{cases}}\)
Vậy.....
d) \(2^{x+1}=32\)
\(2^{x+1}=2^5\)
\(\Rightarrow x+1=5\)
\(\Rightarrow x=4\)
Vậy.....
