Question
Express the following in single exponential form: $(-11)^2 \times(-2)^2$
✓
Answer
We have,$(-11)^2 \times(-2)^2$
$=[(-11) \times(-2)]^2\left[\because a^m \times b^m=(a \times b)^m\right]$
${[\because(-11) \times(-2)=22]}$
$=22^2$
$=[(-11) \times(-2)]^2\left[\because a^m \times b^m=(a \times b)^m\right]$
${[\because(-11) \times(-2)=22]}$
$=22^2$
