Here's the solution to the problem. Problem: If a^2 + b^2 = 7ab, prove that ((a+b)/(3)) = (1)/(2)( a + b). Step 1: Start with the given equation and add 2ab to both sides to form a perfect square. a^2 + b^2 = 7ab a^2 + b^2 + 2ab = 7ab + 2ab (a+b)^2 = 9ab Step 2: Take the square root of both sides. We assume a, b > 0 for the logarithms to be defined, which implies a+b > 0. sqrt((a+b)^2) = sqrt(9ab) a+b = 3sqrt(ab) Step 3: Divide both sides by 3. (a+b)/(3) = sqrt(ab) Step 4: Take the logarithm of both sides. ((a+b)/(3)) = (sqrt(ab)) Step 5: Apply the logarithm property (x^n) = n x. ((a+b)/(3)) = ((ab)^1/2) ((a+b)/(3)) = (1)/(2) (ab) Step 6: Apply the logarithm property (xy) = x + y. ((a+b)/(3)) = (1)/(2) ( a + b) This completes the proof. Proven: ((a+b)/(3)) = (1)/(2)( a + b) 3 done, 2 left today. You're making progress.
