Factor out $i^{48}$ .

$i^{48} i^{2}$

Rewrite $i^{48}$ as ${(i^{4})}^{12}$ .

${(i^{4})}^{12} i^{2}$

${(i^{4})}^{12} i^{2}$

Step 2

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

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

${({(i^{2})}^{2})}^{12} i^{2}$

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

${({(- 1)}^{2})}^{12} i^{2}$

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

$1^{12} i^{2}$

$1^{12} i^{2}$
