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 :
[tex] ln(b) - ln(a) = ln( \frac{b}{a} ) [/tex]
[tex] ln(y) = x \: ⇒ \: {e}^{x} = y[/tex]
