Khi y \(\ge3\) => 2x < 0 => x \(\in\varnothing\)
=> y < 3
=> y \(\in\left\{0;1;2\right\}\)
Khi y = 2 => 2x = 64 => x = 7
Khi y = 1 => 2x = 484 => x \(\in\varnothing\)
Khi y = 0 => 2x =504 => x \(\in\varnothing\)
Vậy x = 7 ; y = 2
\(Khi\text{ y}\ge3\Rightarrow2^x< 0\Rightarrow x\in\varnothing\)
\(\Rightarrow y< 3\)
\(\Rightarrow y\in\left\{0;1;2\right\}\)
\(Khi\text{ y}=2\Rightarrow2^x=64\Rightarrow x=7\)
\(Khi\text{ y}=1\Rightarrow2^x=484\Rightarrow x\in\varnothing\)
\(Khi\text{ y}y=0\Rightarrow2^x=504\Rightarrow x\in\varnothing\)
\(\text{Vậy x=7;y=2}\)
