Question

Simplify-$\frac{3^{-5}\times {10}^5\times {125}^{-1}}{5^{-7}\times 6^{-5}}$

Answer 1

We have,$\frac{3^{-5}\times {10}^5\times {125}^{-1}}{5^{-7}\times 6^{-5}}$

$=\frac{5^7\times 6^5\times {10}^5}{3^5\times {125}^1}$

$=\frac{78125\times 7776\times 100000}{243\times 125}$

$=2000000000$
