Make one hundred (Posted on 2014-05-17) Difficulty: 3 of 5
Create 10 mathematical expressions equal to 100. Each should use as few instances as possible of a single digit (0 through 9.)

You may use any common operation (+, -, *, /, ^, √, !, [], parentheses, concatenation.)

If we can use a decimal point, then nn/.nn = 100 which requires only 4 of each digit.  This works for n = 1...9.  A couple of those could be slightly improved as well:

(.1)^(-1-1) = 100

(2/.2)^2 = 100
