Question

The value of $\frac{i^{592} + i^{590} + i^{588} + i^{586} + i^{584}}{i^{582} + i^{580} + i^{578} + i^{576} + i^{574}} + 2 =$

Open in App

Solution

We know $i^{4 n} = 1$ and $i^{4 n + 2} = - 1$
$\frac{i^{592} + i^{590} + i^{588} + i^{586} + i^{584}}{i^{582} + i^{580} + i^{578} + i^{576} + i^{574}} + 2$
$= \frac{1 + (- 1) + 1 + (- 1) + 1}{(- 1) + 1 + (- 1) + 1 + (- 1)} + 2$
$= - 1 + 2 = 1$
