Question

$${ \left(3 \times \right) }^{ 2 { -2 }^{ 3 } }$$

Answer

$$1/(43046721*^16)$$

Solution


Since the power of 3 is odd, the result will be negative.
\[{(3)}^{2\times -{2}^{3}}\]
Simplify  \({2}^{3}\)  to  \(8\).
\[{(3)}^{2\times -8}\]
Simplify  \(2\times -8\)  to  \(-16\).
\[{(3)}^{-16}\]
Use Negative Power Rule: \({x}^{-a}=\frac{1}{{x}^{a}}\).
\[\frac{1}{{(3)}^{16}}\]
Use Multiplication Distributive Property: \({(xy)}^{a}={x}^{a}{y}^{a}\).
\[\frac{1}{{3}^{16}{}^{16}}\]
Simplify  \({3}^{16}\)  to  \(43046721\).
\[\frac{1}{43046721{}^{16}}\]
