log_{2}(x^2+4)=3

lo g_{2} (x^{2} + 4) = 3

x = 2, x = - 2

Solution steps

lo g_{2} (x^{2} + 4) = 3

Apply log rules

x^{2} + 4 = 8

Solve

x^{2} + 4 = 8 : x = 2, x = - 2

x = 2, x = - 2

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

lo g_{10} (x) = - 1

lo g_{3} (x) + lo g_{3} (x + 1) = 8

0.1 = lo g_{10} (x)

T, - lo g_{10} (T) = 6.016
