Calcula |R| si: R = (1 + i)(81 + 2i) / i - 2

$r = (1 + i)(81 + 2i) \div i - 2$

$r = 81 - 79i$

${r}^{2} = (81 - 79i {)}^{2}$

${x}^{2} + {y}^{2} = (81 - 79i {)}^{2}$

_____________________________________

$|(81 - 79i {)}^{2} |$

$|81 - 79i| {}^{2}$

$\sqrt{ {81}^{2} + ( - 79 {)}^{2} } ^{2}$

$\sqrt{12802} ^{2}$

$\boxed{12802}$
