Simplify i^-5

$i^{- 5}$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{1}{i^{5}}$

Step 2

Simplify the denominator.

Factor out $i^{4}$ .

$\frac{1}{i^{4} i}$

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

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

$\frac{1}{{(i^{2})}^{2} i}$

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

$\frac{1}{{(- 1)}^{2} i}$

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

$\frac{1}{1 i}$

Multiply $i$ by $1$ .

$\frac{1}{i}$
