Solution steps

- 1 = - 2^{x}

Move

2^{x}

to the left side

- 1 + 2^{x} = 0

Move

1

to the right side

2^{x} = 1

Apply exponent rules

x ln (2) = ln (1)

Solve

x ln (2) = ln (1) : x = 0

x = 0

Popular Examples

(100)/(1+e^{-x)}=4

\frac{100}{1 + e ^{- x}} = 4

(100)/(1+e^{-x)}=2

\frac{100}{1 + e ^{- x}} = 2

5*10^{x+2}=5000

5 \cdot 1 0^{x + 2} = 5000

(4^{x+1})/(2^{x+2)}=128

\frac{4 ^{x + 1}}{2 ^{x + 2}} = 128

9^{2 x - 1} = 2187
