The detailed solution for the above-written question is as follows

We know the exponential formula

\frac{a^{m}}{b^{m}} = (\frac{a}{b})^{m}        and   a^{-m}= \frac{1}{a^{m}}  and  (a^{m})^{n} = a^{mn}

 

So, we have given 

a = 1, b=2  

By using above exponential law,

\frac{a^{m}}{b^{m}} = \frac{1}{(2^{3})^{2}} = \frac{1}{2^{6}}

                         = \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}\times \frac{1}{2} = \frac{1}{64}
