Question 1 of 9
Indices + Logs
If 3a = 4, 4b = 5, 5c = 6, 6d = 7, 7e = 8, and 8f = 9, then what is the value of abcdef?
Functions + Quadratic
For any non-zero real x, let f(x) + 2 f(1/x) = 3x. Find the sum of all possible values of x for which f(x) = 3.
Average Problem
The average of three distinct real numbers is 28. If the smallest number is increased by 7 and the largest number is reduced by 10, the order of the numbers remains unchanged, and the new arithmetic mean becomes 2 more than the middle number, while the difference between the largest and the smallest numbers becomes 64. Then, the largest number in the original set of three numbers is _____
