1

We can take out the unknown from the exponent by applying logarithms in base $10$ to both sides of the equation

$\log_{2}\left(2^x\right)=\log_{2}\left(1.5\right)$
2

Use the following rule for logarithms: $\log_b(b^k)=k$

$x=\log_{2}\left(1.5\right)$

Final answer to the problem

$x=\log_{2}\left(1.5\right)$

Exact Numeric Answer

$x=0.585$
