Question

How would you solve this question?

Answer 1

Answer:

The value of a is e³ and b is e.

The steps are :

First, you have to integrate the expression shown in the first picture.

Next, you have to solve it as simultaneous equation shown in the second picture.

You have to apply :

$ln(b) - ln(a) = ln( \frac{b}{a} )$

$ln(y) = x \: ⇒ \: {e}^{x} = y$
