I have an original solution. It's not mathematical. Here's how I solved this:

Write 1 7 7 and rotate two other 7s like letter L and put them together with recently written 7s. 1L7L7 :)

100 - Back to the Number Puzzles

Using four sevens (7) and a one (1) create the number 100. Except the five numerals you can use the usual mathematical operations (+, -, x, :), root and brackets ().

100 - solution

100 = 177-77 = (7+7)x(7+(1:7))

I do not know other solutions.
