\(\frac{33.44^2+55^3.33}{45.33^2-99.33^4}\)

Answer 1

[minhduc]

\(\frac{33.44^2+55^3.33}{45.33^2-99.33^4}\)

\(=\frac{33.121.16+121.25.33}{5.9.33^2-11.9.33^2.33^2}\)

\(=\frac{33.121\left(16+25\right)}{1089.9.\left(5-11.1089\right)}\)

\(=\frac{3993.41}{9801.\left(-11974\right)}\)

\(=-\frac{163713}{117357174}\).

Answer 2

[💛Linh_Ducle💛]

\(\frac{33.44^2+55^3.33}{45.33^2-99.33^4}\)

=\(\frac{33.\left(4.11\right)^2+\left(5.11\right)^3.33}{9.5.33^2-9.11.33^4}\)

=\(\frac{33.16.11^2+125.11^3.33}{33^2.9.\left(5-11.33^2\right)}\)

= \(\frac{33.11^2.\left(16+125.11\right)}{33^2.9.\left(-11974\right)}\)

= \(\frac{132.1391}{33.9.\left(-107766\right)}\)

=  \(\frac{183612}{-32006502}\)
