Question

What is the value of x in the equation below? 1+2eX+1 = 9

Answer 1

The value of x is 1.252762968495368

Solution:

Given that,

We have to find the value of x in given equation

Given equation is:

$1+2e^x + 1 = 9$

Simplify the left side of equation

$2+2e^x = 9$

Move 2 from left side to right side of equation

$2e^x = 9-2\\\\2e^x= 7$

Therefore,

$e^x = \frac{7}{2}\\\\e^x = 3.5$

Taking ln on both sides

ln and e cancels each other each other

$x = ln\ 3.5$

Therefore,

x = 1.252762968495368

Thus the value of x is found
