Answer:

$18 {j}^(5) {k}^(10)$

Explanation:

Given:

$a (area) = 144 {j}^(9) {k}^(15)$

$w(width) = 8 {j}^(4) {k}^(5)$

Find: l (length) - ?

.

In order to find the length, we have to divide the area from the width (since a = w × l):

.

$l = \frac{144 {j}^(9) {k}^(15) }{8 {j}^(4) {k}^(5) } = \frac{18 {j}^(9) {k}^(15) }{ {j}^(4) {k}^(5) } = 18 {j}^(5) {k}^(10)$

Use power properties (when dividing equal bases raised to different powers, power indicators are subtracted)
