log_{10}(sqrt(x^2-21x))=1

lo g_{10} (x^{2} - 21 x) = 1

x = 25, x = - 4

Solution steps

lo g_{10} (x^{2} - 21 x) = 1

Apply log rules

x^{2} - 21 x = 10

Solve

x^{2} - 21 x = 10 : x = 25, x = - 4

x = 25, x = - 4

k, p k = - lo g_{10} (k)

lo g_{3} (12 x - 12) = 2 + lo g_{3} (x)

20 = 3 lo g_{2} (1 + x)

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

x, y - 2 = ln (x + e^{2})
