I was watching a video on youtube about how colors work in computers, and found this statement:
"The average of two square roots is less than the square root of an average"
The link to the video where I found this: here
There's even an image in the video with the corresponding algebraic expression, even though in the image it's using a <= (less or equal) sign, instead of a < (less than) sign.
Could someone proof how this makes sense?
P.S. Sorry I don't include the expression in this question, I don't know how to.
