ln (x^{2} - 9) = 0

x = 10, x = - 10

Decimal Notation

x = 3.16227 \dots, x = - 3.16227 \dots

Solution steps

ln (x^{2} - 9) = 0

Apply log rules

x^{2} - 9 = 1

Solve

x^{2} - 9 = 1 : x = 10, x = - 10

x = 10, x = - 10

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

lo g_{2} (x + 1) = 4

ln (\frac{3}{t - 5}) = 1.92

ln (x - 2) = 0

lo g_{4} (2 x - 10) = \frac{1}{2}
