Question
Find the following product:
$1.5 a\left(10 a^2 b-100 a b^2\right)$
$1.5 a\left(10 a^2 b-100 a b^2\right)$
✓
Answer
$=1.5 a \times 10 a^2 b-1.5 a \times 100 a b^2$
$=1.5 \times 10 \times a \times a^2 b-1.5 \times 100 \times a \times a \times b^2$
$=15 \times a^{(1+2)} b-150 \times a^{(1+1)} \times b^2$
$=15 a^3 b-150 a^2 b^2$
$=1.5 \times 10 \times a \times a^2 b-1.5 \times 100 \times a \times a \times b^2$
$=15 \times a^{(1+2)} b-150 \times a^{(1+1)} \times b^2$
$=15 a^3 b-150 a^2 b^2$
