Question

Solve the following logarithmic equation. Express irrational solutions in exact form and as a rounded decimal. Verify your results using a graphing utility. In x + In (x + 12) = 4 What is the exact solution? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The solution set is { }. (Simplify your answer. Type an exact answer. Use a comma to separate answers as needed.) OB. There is no solution. What is the decimal approximation of the solution? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The solution set is { }. (Round to three decimal places as needed. Use a comma to separate answers as needed.) O B. There is no solution.

Answer 1

Solution Given: lux + ln (4+12) = 4 FORMULA: In A + ln B= ln (A.B) | . en [x (x+1)] = 4 x(x - 12) = x x² + 12x = 54.6 x2 +122-54.6 = 0 A = 3.518 OR. Taz – 15.52 The solution set is [3.518 & 18.52)

(3.518, 0) N in(x) +ln(x + 12)-4
