Question

ln(8x-1)=2 ?

Answer 1

Solve the equation for x. Write the exact solution and the approximate solution to the nearest hundredth, when appropriate.

Answer 2

the invrse operation of ln(x) is e^x so the first step is taking e^(both sides), giving:

\[e^{\ln(8x -1)}\]

Answer 3

ok

Answer 4

\[e^{(\ln(8x -1)} = 8x - 1 = e^2 \]

Answer 5

and you'd solve for x normally, taking the e^2 value from calculator

Answer 6

i dont have an advanced calculator

Answer 7

but i got it thanx
