Problem

Find the solution of the exponential equation $e^{2 x+1}=31$ in terms of logarithms, or correct to four decimal places. \[ x= \] Question Help: $\square$ Video Submit Question Jump to Answer

Solution

Step 1 :The given equation is \(e^{2x+1} = 31\).

Step 2 :Take the natural logarithm (ln) on both sides of the equation to bring down the exponent on the left side: \(ln(e^{2x+1}) = ln(31)\).

Step 3 :This simplifies to \(2x + 1 = ln(31)\).

Step 4 :Isolate x by subtracting 1 and dividing by 2: \(x = \frac{ln(31) - 1}{2}\).

Step 5 :Using a calculator, we find that \(x = 1.2169936022425731\).

Step 6 :Final Answer: The solution to the equation \(e^{2 x+1}=31\) is \(x=\boxed{1.2169936022425731}\), correct to four decimal places.
