ln(x+7)+ln(x+3)=ln(77)

ln (x + 7) + ln (x + 3) = ln (77)

x = 4

Solution steps

ln (x + 7) + ln (x + 3) = ln (77)

Apply log rules

(x + 7) (x + 3) = 77

Solve

(x + 7) (x + 3) = 77 : x = 4, x = - 14

x = 4, x = - 14

Verify Solutions:

x = 4

True

, x = - 14

False

The solution is

x = 4

2 ln (6 x) = 6

x, lo g_{e} (x + 1) = y + C

lo g_{10} (x) - lo g_{10} (x + 4) = 1

ln (a) = 722

ln (T) = 1.56 + 0.82 \cdot ln (11)
