Solution for ln(x+3)-lnx=5ln(x^2-4) equation:


Simplifying
ln(x + 3) + -1lnx = 5ln(x2 + -4)

Reorder the terms:
ln(3 + x) + -1lnx = 5ln(x2 + -4)
(3 * ln + x * ln) + -1lnx = 5ln(x2 + -4)
(3ln + lnx) + -1lnx = 5ln(x2 + -4)

Combine like terms: lnx + -1lnx = 0
3ln + 0 = 5ln(x2 + -4)
3ln = 5ln(x2 + -4)

Reorder the terms:
3ln = 5ln(-4 + x2)
3ln = (-4 * 5ln + x2 * 5ln)
3ln = (-20ln + 5lnx2)

Solving
3ln = -20ln + 5lnx2

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '20ln' to each side of the equation.
3ln + 20ln = -20ln + 20ln + 5lnx2

Combine like terms: 3ln + 20ln = 23ln
23ln = -20ln + 20ln + 5lnx2

Combine like terms: -20ln + 20ln = 0
23ln = 0 + 5lnx2
23ln = 5lnx2

Add '-5lnx2' to each side of the equation.
23ln + -5lnx2 = 5lnx2 + -5lnx2

Combine like terms: 5lnx2 + -5lnx2 = 0
23ln + -5lnx2 = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(23 + -5x2) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2

Set the factor '(23 + -5x2)' equal to zero and attempt to solve: Simplifying 23 + -5x2 = 0 Solving 23 + -5x2 = 0 Move all terms containing l to the left, all other terms to the right. Add '-23' to each side of the equation. 23 + -23 + -5x2 = 0 + -23 Combine like terms: 23 + -23 = 0 0 + -5x2 = 0 + -23 -5x2 = 0 + -23 Combine like terms: 0 + -23 = -23 -5x2 = -23 Add '5x2' to each side of the equation. -5x2 + 5x2 = -23 + 5x2 Combine like terms: -5x2 + 5x2 = 0 0 = -23 + 5x2 Simplifying 0 = -23 + 5x2 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
