e^t-e^{-t}=2

Solution

e^{t} - e^{- t} = 2

Solution

t = ln (1 + 2)

+1

Decimal

t = 0.88137 \dots

Solution steps

e^{t} - e^{- t} = 2

Apply exponent rules

e^{t} - (e^{t})^{- 1} = 2

Rewrite the equation with

e^{t} = u

u - (u)^{- 1} = 2

Solve

u - u^{- 1} = 2 : u = 1 + 2, u = 1 - 2

u = 1 + 2, u = 1 - 2

Substitute back

u = e^{t},

solve for

t

Solve

e^{t} = 1 + 2 : t = ln (1 + 2)

Solve

e^{t} = 1 - 2 :

No Solution for

t \in R

t = ln (1 + 2)

81*9^{-2b-2}=27

81 \cdot 9^{- 2 b - 2} = 27

63 = 3 3^{x}

9^6=(3^2)^{2x-2}

9^{6} = (3^{2})^{2 x - 2}

6^x=3^{2x}-2^{2x}

6^{x} = 3^{2 x} - 2^{2 x}
