Question

$$9 { \times }^{ { 2 }^{ -81 } }$$

Answer

$$9*^(1+1/(2.4178516392293*10^24))$$

Solution


Use Negative Power Rule: \({x}^{-a}=\frac{1}{{x}^{a}}\).
\[9{\sqrt[2}^{81]{}}\]
Simplify  \({2}^{81}\)  to  \(2.417852\times {10}^{24}\).
\[9\sqrt[2.417852\times {10}^{24]{}}\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[9{}^{1+\frac{1}{2.417852\times {10}^{24}}}\]
