Simplify i^97-i

$i^{97} - i$

Step 1

Simplify each term.

Rewrite $i^{97}$ as ${(i^{4})}^{24} i$ .

Factor out $i^{96}$ .

$i^{96} i - i$

Rewrite $i^{96}$ as ${(i^{4})}^{24}$ .

${(i^{4})}^{24} i - i$

${(i^{4})}^{24} i - i$

Rewrite $i^{4}$ as $1$ .

Rewrite $i^{4}$ as ${(i^{2})}^{2}$ .

${({(i^{2})}^{2})}^{24} i - i$

Rewrite $i^{2}$ as $- 1$ .

${({(- 1)}^{2})}^{24} i - i$

Raise $- 1$ to the power of $2$ .

$1^{24} i - i$

$1^{24} i - i$

One to any power is one.

$1 i - i$

Multiply $i$ by $1$ .

$i - i$

$i - i$

Step 2
