Question

plzz help 4 solve these sums .....chptr complex numbers...plzz ..fast..tommarow will be my test..

Answer 1

I think this will be 1/ i^71

Answer 2

$i = \sqrt{ - 1}$
$i {2 = - 1}^{?}$


$i {3 = - 1}^{?}$

jse this values u can solve..it.......___________ 4e.g 1.
$i7 = i {4 \times i {3 = - 1 \times \sqrt{ - 1 = - i} }^{?} }^{?}$
