Question
Multiply the following:$-\frac{100}{9}\text{rs};\frac{3}{4}\text{r}^3\text{s}^2$
✓
Answer
$-\frac{100}{9}\text{rs};\frac{3}{4}\text{r}^3\text{s}^2$$-\frac{100}{9}\text{rs}\times\frac{3}{4}\text{r}^3\text{s}^2$ $=(-\frac{100}{9}\times\frac{3}{4})\text{rs}\times\text{r}^3\text{s}^2$
$=-\frac{25}{3}\times\text{r}^4\text{s}^3$
$=-\frac{25}{3}\times\text{r}^4\text{s}^3$
