Solution by Steps
step 2
Apply the negative exponent rule: (54b10)6=1(54b10)6\left(5^{4} \cdot b^{-10}\right)^{-6} = \frac{1}{\left(5^{4} \cdot b^{-10}\right)^{6}}
step 3
Simplify the exponent: (54b10)6=546b106=524b60\left(5^{4} \cdot b^{-10}\right)^{6} = 5^{4 \cdot 6} \cdot b^{-10 \cdot 6} = 5^{24} \cdot b^{-60}
step 4
Combine the results: 1524b60=b60524\frac{1}{5^{24} \cdot b^{-60}} = \frac{b^{60}}{5^{24}}
C
Key Concept
