The area of a rectangle is equal to its width times its length. To find the width given the area, divide the area by the length. I’ll break this down for each term...

(48x^3y^7) / (12xy^4)
48/4=12
X^3 / X = X^2 (subtract exponential values when dividing)
Y^7 / Y^4 = Y^3 (subtract exponential values when dividing)

To find the length of the cube when given the volume, divide by the product of the width and height (heigh times width).
The product of the width and the height is 30x^7y^6.

60/30=2
X^16/x^7=x^9
Y^9/y^6=y^3
Z^5/1=z^5
