Simplifying ln(x2 + 1) = 4 Reorder the terms: ln(1 + x2) = 4 (1 * ln + x2 * ln) = 4 (1ln + lnx2) = 4 Solving 1ln + lnx2 = 4 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Reorder the terms: -4 + 1ln + lnx2 = 4 + -4 Combine like terms: 4 + -4 = 0 -4 + 1ln + lnx2 = 0 The solution to this equation could not be determined.
