log_{10}(x^2-15x)=3

lo g_{10} (x^{2} - 15 x) = 3

x = 40, x = - 25

Solution steps

lo g_{10} (x^{2} - 15 x) = 3

Apply log rules

x^{2} - 15 x = 1000

Solve

x^{2} - 15 x = 1000 : x = 40, x = - 25

x = 40, x = - 25

ln (x) = 2

ln (x - a) + ln (x) = 1

ln (7 x) = - 2

lo g_{10} (x - 4) = 2

lo g_{10} (10 x) = - 2
