log_{10}(x^2+15x)=2

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

x = 5, x = - 20

Solution steps

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

Apply log rules

x^{2} + 15 x = 100

Solve

x^{2} + 15 x = 100 : x = 5, x = - 20

x = 5, x = - 20

lo g_{9} (9) = 2 lo g_{9} (x)

lo g_{x} (- x + 90) = 2

lo g_{4} (3 x - 8) = 1

lo g_{2} (x) + lo g_{2} (4 x) - 6 = 0

lo g_{x + 3} (3 x^{2} - 2 x + 9) = 2
