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.)

So far 6,7,8 stay with the generic solution, using 6 digits to get 100:
100=(kkk-kk)/k..... k=6, 7, 8.
Will try to improve it.
