$\log _{2} \frac{\sqrt{x}}{a^{2}}$
So, the simplified form of the expression \(\log _{2} \frac{\sqrt{x}}{a^{2}}\) is \(\boxed{-2\log(a) + 0.5\log(x)}\)
Step 1 :Given the expression \(\log _{2} \frac{\sqrt{x}}{a^{2}}\)
Step 2 :We can use the properties of logarithms to simplify this expression.
Step 3 :Applying the property \(\log_b(m/n) = \log_b(m) - \log_b(n)\), we get \(-\log(a^{2}) + \log(\sqrt{x})\)
Step 4 :Next, applying the property \(\log_b(m^n) = n \log_b(m)\), we get \(-2\log(a) + 0.5\log(x)\)
Step 5 :So, the simplified form of the expression \(\log _{2} \frac{\sqrt{x}}{a^{2}}\) is \(\boxed{-2\log(a) + 0.5\log(x)}\)
