Simplifying an expression with expression with exponents:
If they are dividing, we keep the base and subtract the exponents. For example:

In this question:
Answer:

Step-by-step explanation:
Given differential equation,


Let y = vx
Differentiating with respect to x,

From equation (1),








Integrating both sides,




Now, y = vx ⇒ v = y/x

4x = 6x -10
2x = 10
x = 5
answer
x = 5
