2^x+2=2^50-2^3
2^x+2=2^47
suy ra x+2=47
x=47-2
x=45
\(2^{x+2}=2^{50:8}\)
\(2^{x+2}=2^{\frac{25}{4}}\)
\(\Rightarrow x+2=\frac{25}{4}\)
\(\Rightarrow x=\frac{25}{4}-2\)
\(\Rightarrow x=\frac{17}{4}\)
Vậy \(x=\frac{17}{4}\)
( don't k .....#EXOComingsoon....)
\(2^{x+2}=2^{50}:8\Leftrightarrow2^{x+2}=2^{50}:2^3\)
\(2^{x+2}=2^{50-3}=2^{47}=2^{45+2}\Rightarrow x=45\)
