Question
Express in exponential form: $2 \times 2 \times a \times a$
✓
Answer
We have,
$2 \times 2 \times a \times a$
$=2^{1+1} \times a^{1+1}$[ Bases are same, powers are added]
$=2^2 \times a^2$
$2 \times 2 \times a \times a$
$=2^{1+1} \times a^{1+1}$[ Bases are same, powers are added]
$=2^2 \times a^2$
