1+2e^{x+1}=9

Solution

1 + 2 e^{x + 1} = 9

Solution

x = 2 ln (2) - 1

+1

Decimal Notation

x = 0.38629 \dots

Solution steps

1 + 2 e^{x + 1} = 9

Move

1

to the right side

2 e^{x + 1} = 8

Divide both sides by

2

e^{x + 1} = 4

Apply exponent rules

x + 1 = ln (4)

Solve

x + 1 = ln (4) : x = 2 ln (2) - 1

x = 2 ln (2) - 1

Popular Examples

4^{x - 1} = 3

x^{7} = 7^{x}

e^{1-2x}=e^{3x-5}

e^{1 - 2 x} = e^{3 x - 5}

8^{2x+3}=2^ab^x

8^{2 x + 3} = 2^{a} b^{x}

e^{5 l n (x)} = 32
