solvefor x,ln(x+7)+ln(x-7)=0

solve for

x, ln (x + 7) + ln (x - 7) = 0

x = 52

Decimal Notation

x = 7.07106 \dots

Solution steps

ln (x + 7) + ln (x - 7) = 0

Apply log rules

(x + 7) (x - 7) = 1

Solve

(x + 7) (x - 7) = 1 : x = 52, x = - 52

x = 52, x = - 52

Verify Solutions:

x = 52

True

, x = - 52

False

The solution is

x = 52

7 = 3 lo g_{10} (8 t + 10)

ln (e - x + 7 + 3) = 50

x, lo g_{4} (x + y) = 3

ln (x) + ln (2 x - 1) = 0

lo g_{4} (x^{2}) = 5 lo g_{4} (x) - 4
