log_{2}(-5x)=4

lo g_{2} (- 5 x) = 4

x = - \frac{16}{5}

Decimal Notation

x = - 3.2

Solution steps

lo g_{2} (- 5 x) = 4

Apply log rules

- 5 x = 16

Solve

- 5 x = 16 : x = - \frac{16}{5}

x = - \frac{16}{5}

3 ln (x - 2) = 18

e (x) = ln (x)

lo g_{5} (x + 7) = 2

lo g_{3} (x + 7) - lo g_{3} (x + 1) = 3

lo g_{10} (x) = - 1.45
