Answer 1

\(\frac{10^4.81-16.15^2}{4^4.675}=\frac{\left(2.5\right)^4.3^4-2^4\left(3.5\right)^2}{2^8.5^2.3^3}=\frac{2^4.3^2.5^2\left(5^2.3^2-1\right)}{2^8.5^2.3^3}=\frac{255-1}{16.3}=\frac{14}{3}\)

Answer 2

$\frac{10^4.81-16.15^2}{4^4.675}=\frac{10^4.3^4-4^2.15^2}{4^4.5^4}=\frac{30^4-60^2}{20^4}=\frac{900^2-60^2}{400^2}=\frac{20^2\left(45^2-3^2\right)}{20^2.2^2}=\frac{2016}{4}=504$104.81−16.15244.675 =‍104.34−42.15244.54 =304−602204 =9002−6024002 =202(452−32)202.22 =20164 =504
