7 with three 2s
How can you get 7 using only three 2s. You can use plus, minus, multiply, divide, square root, factorial, decimal point, log, “to the power of” and parentheses. As many times as you want. You can also put digits together to form … let’s say 22.
sqrt(.2^-2)+2 = 7
Very well done!!! Unintuitive but accurate answer… Deserves bonus points
