ln (1 - 2 x) = 0.4

x = - \frac{e ^{0.4} - 1}{2}

Solution steps

ln (1 - 2 x) = 0.4

Apply log rules

1 - 2 x = e^{0.4}

Solve

1 - 2 x = e^{0.4} : x = - \frac{e ^{0.4} - 1}{2}

x = - \frac{e ^{0.4} - 1}{2}

lo g_{10} (x^{3} + 2000) = 2

ln (x + 4) - ln (x - 6) = 1

lo g_{2} (x + 1) = 1 - lo g_{2} (x)

lo g_{5} (4 x + 1) = 2

lo g_{5} (x + 3) + lo g_{5} (x) = 2
