2^{- x} = 1.5

x = - \frac{ln ( 1.5 )}{ln ( 2 )}

Decimal Notation

x = - 0.58496 \dots

Solution steps

2^{- x} = 1.5

Apply exponent rules

- x ln (2) = ln (1.5)

Solve

- x ln (2) = ln (1.5) : x = - \frac{ln ( 1.5 )}{ln ( 2 )}

x = - \frac{ln ( 1.5 )}{ln ( 2 )}

2 x + e^{x} = 0

x, e^{x + y} = e^{x} + e^{y}

128 = 2^{x}

e^{- x} + \frac{1}{5} x - 1 = 0

(\frac{1}{3})^{x} = 243
