Simplify i^20*i^41

$i^{20} \cdot i^{41}$

Step 1

Rewrite $i^{20}$ as ${(i^{4})}^{5}$ .

${(i^{4})}^{5} \cdot i^{41}$

Step 2

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

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

${({(i^{2})}^{2})}^{5} \cdot i^{41}$

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

${({(- 1)}^{2})}^{5} \cdot i^{41}$

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

$1^{5} \cdot i^{41}$

$1^{5} \cdot i^{41}$

Step 3

One to any power is one.

$1 \cdot i^{41}$
