What is \(x\)?

\(2^x-2^{x-2}=3(2^{13})\)

\(\Rightarrow 2^x-\frac{2^x}{2^2}=3(2^{13})\)

\(\Rightarrow \frac{2^22^x-2^x}{2^2}=3(2^{13})\)

\(\Rightarrow \frac{2^x(2^2-1)}{2^2}=3(2^{13})\)

\(\Rightarrow 2^x(4-1)=3(2^{13})(2^2)\)

\(\Rightarrow 3(2^x)=3(2^{15})\)

\(\Rightarrow 2^x=2^{15}\)

\(\Rightarrow x=15\)

Note: I could not see the image properly, I think the second half of the question had \(x^{13}\). If the value was other than 13 then the answer would be that value + 2.
