Final answer:
The other dimension of the rectangle is 4x^3y^3 - 3y.
Step-by-step explanation:
To find the other dimension of the rectangle, we can use the formula for the area of a rectangle which is length times width. Given that one dimension is 2x^3y^4, we can substitute this into the formula:
Area = 8x^6y^7 - 6x^5y^5
8x^6y^7 - 6x^5y^5 = 2x^3y^4 * width
Divide both sides by 2x^3y^4 to solve for the width:
width = (8x^6y^7 - 6x^5y^5) / (2x^3y^4)
Simplifying the expression:
width = 4x^3y^3 - 3y
Therefore, the other dimension of the rectangle is 4x^3y^3 - 3y.
