Question

Solve:
$\frac{{15}^3\times {18}^2}{3^5\times 5^4\times {12}^2}$

Answer 1

To solve : $\frac{{15}^3\times {18}^2}{3^5\times 5^4\times {12}^2}$

$=\frac{(5\times 3{)}^3\times (3^2\times 2{)}^2}{3^5\times 5^4\times (2^2\times 3{)}^2}$

$=\frac{5^3\times 3^7\times 2^4}{3^7\times 5^4\times 2^4}$

$=5^{-1}=\frac{1}{5}$
