Question

(2a^2 b^3)(6a^-3 b^-3) help to simplify how do u get 12/ab^2

Answer 1

$\huge\mathcal{Answer \ :-}$

$\mathsf{Given \ :-}$

$({2 {a}^{2} {b}^{3} })({6 {a}^{ - 3} {b}^{ - 3} })$
$\mathsf{Using \ identity}$

${x}^{ - m} = \frac{1}{ {x}^{m} }$
•°•

$\frac{(2 {a}^{2} {b}^{3} )( 6)}{ {a}^{3} {b}^{3} }$
$\mathsf{On \ expanding, \ we \ get}$

$\frac{2 \times a \times a \times b \times b \times b \times 6}{a \times a \times a \times b \times b \times b}$

$\mathsf{On \ cancelling, \ we \ get}$

$\frac{2 \times 6}{a} \\ \\ \frac{12}{a}$
$\mathsf\green{The \ answer \ is \ 12/a.}$

$\huge\mathbb{Hope \ this \ helps.}$
