I believe you meant to type In((3x-5)^1/2 )/7. See the difference. You forgot to raise (3x - 5) to the 1/2 power. Use the log rule for division: ln(a/b) = ln(a) - ln(b). ln((3x - 5)^1/2) - ln(7) Note: (3x - 5)^1/2 is sqrt{3x - 5} in disguise. Answer: ln(s...

x^2 + 14x + k k = [14(1/2)]^2 k = (7)^2 k = 7 times 7 k = 49
