0. 8^{x} = 0.4

x = \frac{ln ( 0.4 )}{ln ( 0.8 )}

Solution steps

0. 8^{x} = 0.4

Apply exponent rules

x ln (0.8) = ln (0.4)

Solve

x ln (0.8) = ln (0.4) : x = \frac{ln ( 0.4 )}{ln ( 0.8 )}

x = \frac{ln ( 0.4 )}{ln ( 0.8 )}

0. 8^{x} = 0.5

e^{3.7 t} = 9.7

x, 2^{- x} = 10

y, 2 x = e^{y} - e^{- y}

3125 = 2^{x}
