Question

Solve the equation for x and round your answer to the nearest hundreth.
5 = ln(x + 1)

Answer 1

Use the definition of ln.

\( \ln x = y\) means that \(e^y = x\).

Answer 2

I don't know what it is!

Answer 3

I've tried

Answer 4

Use the definition of ln,

if \(\ln x = y\), then \(e^y = x\)

with your problem.

\( 5 = \ln(x + 1) \)

\( \ln (x + 1) = 5\) means \(e^5 = x + 1\).

\(e^5\) is just a number, so solve the equation

\(e^5 = x + 1\) for x. (Hint: subtract 1 from both sides.)
