Question

Find out the product of:

$\left(\frac{2}{3}ab\right)$ and $\left(\frac{-15}{8}{a}^2{b}^2\right)$

Answer 1

We need to find product of $\left(\frac{2}{3}ab\right)$ and $\left(\frac{-15}{8}{a}^2{b}^2\right)$

Their product is $\frac{2}{3}\times (-\frac{15}{8})(a\times a^2)(b\times b^2)$

$=\frac{2}{3}\times (-\frac{15}{8})a^{1+2}{b}^{1+2}$

$=-\frac{5}{4}{a}^3{b}^3$
