This is more of a question about a symbol, rather than a question about a problem.
I keep seeing 7√2 and I'm just wondering if the number outside of the radical is being multiplied by the square root, or if there is a deeper meaning. I can't really explain well, but if the square root of 2 is about 1.41 then would I multiply 1.41 by 7 to get 9.87? Or..?
