I have searched the net for an online calculator to figure out this problem. Your expertise would help! An investment of 3 million dollars is expected to become 6 million dollars in ten years. What is the expected rate of return? Thanks. John in San Antonio

I use Google as a calculator for these kinds of problems. Just type in (6000000/3000000)^(1/10) and you'll get 1 + rate of return.

If I was putting it into Google for myself I'd use 2^.1, which is even shorter. But for pedagogical purposes I left everything unsimplified.
