Solution by Steps
step 2
Apply the negative exponent rule: (3366)3=1(3366)3\left(3^{3} \cdot 6^{6}\right)^{-3} = \frac{1}{\left(3^{3} \cdot 6^{6}\right)^{3}}
step 3
Simplify the exponent: (3366)3=333663=39618\left(3^{3} \cdot 6^{6}\right)^{3} = 3^{3 \cdot 3} \cdot 6^{6 \cdot 3} = 3^{9} \cdot 6^{18}
step 4
Combine the results: 139618\frac{1}{3^{9} \cdot 6^{18}}
Key Concept
Negative Exponent Rule
When an expression with a product is raised to a negative exponent, it is equivalent to the reciprocal of the expression raised to the positive exponent.
