e^x+6e^{-x}-5=0

Solution

e^{x} + 6 e^{- x} - 5 = 0

Solution

x = ln (3), x = ln (2)

+1

Solution steps

e^{x} + 6 e^{- x} - 5 = 0

Apply exponent rules

e^{x} + 6 (e^{x})^{- 1} - 5 = 0

Rewrite the equation with

e^{x} = u

u + 6 (u)^{- 1} - 5 = 0

Solve

u + 6 u^{- 1} - 5 = 0 : u = 3, u = 2

u = 3, u = 2

Substitute back

u = e^{x},

solve for

x

Solve

e^{x} = 3 : x = ln (3)

Solve

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

x = ln (3), x = ln (2)
