Final Answer: The solution to the equation e2x+1=31 is x=1.2169936022425731, correct to four decimal places.

Steps

Step 1 :The given equation is e2x+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(e2x+1)=ln(31).

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

Step 4 :Isolate x by subtracting 1 and dividing by 2: x=ln(31)12.

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

Step 6 :Final Answer: The solution to the equation e2x+1=31 is x=1.2169936022425731, correct to four decimal places.
