e^{2x}-6e^x+8=0

Solution

e^{2 x} - 6 e^{x} + 8 = 0

Solution

x = 2 ln (2), x = ln (2)

+1

Solution steps

e^{2 x} - 6 e^{x} + 8 = 0

Apply exponent rules

(e^{x})^{2} - 6 e^{x} + 8 = 0

Rewrite the equation with

e^{x} = u

(u)^{2} - 6 u + 8 = 0

Solve

u^{2} - 6 u + 8 = 0 : u = 4, u = 2

u = 4, u = 2

Substitute back

u = e^{x},

solve for

x

Solve

e^{x} = 4 : x = 2 ln (2)

Solve

e^{x} = 2 : x = ln (2)

x = 2 ln (2), x = ln (2)
