Question

find the value of :- i+i²+i³+i⁴​

Answer 1

$\bold{→i +{i}^{2} + {i}^{3} + {i}^{4} }$

$\bold{ = \sqrt{ - 1} +{ (\sqrt{ - 1}) }^{2} + { (\sqrt{ - 1}) }^{3} + { (\sqrt{ - 1} )}^{4} }$

$\bold{= \purple{\cancel{\sqrt{ -1}}} - \cancel{1} - \purple{ \cancel{\sqrt{ - 1}} } + \cancel{1} }$

$\bold{\red{= 0}}$
