x + 1/2 = 25 : 23 = 22
x = 4 - 1/2 = 3,5
\(\Rightarrow x+\frac{1}{2}=4\)
\(\Rightarrow x=\frac{7}{2}\)
Vậy \(x=\frac{7}{2}\)
\(x+\frac{1}{2}=2^5:2^3\)
\(\Rightarrow x+\frac{1}{2}=2^2\)
\(\Rightarrow x+\frac{1}{2}=4\)
\(\Rightarrow x=4-\frac{1}{2}\)
\(\Rightarrow x=\frac{7}{2}\)
Vậy \(x=\frac{7}{2}.\)
