Simplifying ln(x) + ln(7x) = 2 Multiply ln * x lnx + ln(7x) = 2 Remove parenthesis around (7x) lnx + ln * 7x = 2 Reorder the terms for easier multiplication: lnx + 7ln * x = 2 Multiply ln * x lnx + 7lnx = 2 Combine like terms: lnx + 7lnx = 8lnx 8lnx = 2 Solving 8lnx = 2 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Divide each side by '8nx'. l = 0.25n-1x-1 Simplifying l = 0.25n-1x-1
