$\boxed{{\red{C}}{\blue{o}}{\pink{n}}{\purple{t}}{\green{a}}\orange{ \: a}{\red{r}}{\blue{m}}{\pink{a}}{\purple{d}}{\green{a}}\orange{ \: ♡}}$

$\bf{{\red{( + 4x {}^{2}) \times ( + 5x {}^{3} )}}} \\ \bf{{\red{4x {}^{2} \times (5x {}^{2}) }}} \\ \bf{{\red{4x {}^{2} \times 5x {}^{3} }}} \\ \bf{{\red{20x {}^{2} \times x {}^{3} }}} \\ \bf{{\red{20 x{}^{2 + 3} }}} \\ \bf{{\red{20x {}^{5} }}}$

${\red{E}}{\blue{x}}{\pink{p}}{\purple{l}}{\green{i}}\orange{c}{\red{a}}{\blue{ç}}{\pink{ã}}{\purple{o}}{\green{ \: ♡}}\orange{♡}$
