log_{2}(x-3)=-1

lo g_{2} (x - 3) = - 1

x = \frac{7}{2}

Decimal Notation

x = 3.5

Solution steps

lo g_{2} (x - 3) = - 1

Apply log rules

x - 3 = \frac{1}{2}

Solve

x - 3 = \frac{1}{2} : x = \frac{7}{2}

x = \frac{7}{2}

50 = 12.751 ln (x) + 18.864

lo g_{10} (5 - x) = 3

1 + lo g_{4} (t) = 6 lo g_{t} (16)

x + ln (x) = 10

lo g_{5} (125 x) = \frac{5}{3}
