15-e^{x-8}=4

Solution

15 - e^{x - 8} = 4

Solution

x = ln (11) + 8

+1

Decimal Notation

x = 10.39789 \dots

Solution steps

15 - e^{x - 8} = 4

Move

15

to the right side

- e^{x - 8} = - 11

Divide both sides by

- 1

e^{x - 8} = 11

Apply exponent rules

x - 8 = ln (11)

Solve

x - 8 = ln (11) : x = ln (11) + 8

x = ln (11) + 8

e^{-x}+e^{-2x}= 2/3

e^{- x} + e^{- 2 x} = \frac{2}{3}

4^x-12\times 2^x+32=0

4^{x} - 12 \times 2^{x} + 32 = 0
