Short Answer

Expert verified

The simplified value of expression is $- 24 r^{7} s^{5}$ .

Step by step solution

Step 1. Write down the given expression.

The given expressiomn to simplify is ${(- 2 r^{2} s)}^{3} (3 r s^{2})$ .

Step 2. Simplify the given expression.

Simplifying ${(- 2 r^{2} s)}^{3} (3 r s^{2})$ gives,

$\begin{matrix} {(- 2 r^{2} s)}^{3} (3 r s^{2}) = {(- 2)}^{3} {(r^{2} s)}^{3} (3 r s^{2}) \\ = - 8 {(r)}^{6} {(s)}^{3} (3) (r) {(s)}^{2} \\ = (- 8 \times 3) {(r)}^{6 + 1} {(s)}^{3 + 2} .... (Using x^{a} \times x^{b} = x^{a + b}) \\ = - 24 r^{7} s^{5} \end{matrix}$

Step 3. Conclusion.

The simplified value of expression is $- 24 r^{7} s^{5}$ .
