Question

Suppose ln(x^2 - 1) = 9

Express the equation in the exponential form e^A = B. Use the variable x as necessary in your answer

Answer 1

ln(x^2-1)=9 -> x^2-1=e^9 and manipulate all you want from there

Answer 2

yeah thats what i got so far but how do i solve for x?

Answer 3

Isolate variable x :
x² = 1 + e^9 = ..
Can you solve now?

Answer 4

x=sqrt(1+e^9) that is the exact answer
