Answer:
( 7 + 7 ) * ( 7 + 1/7) = 100
177 - 77 = 100
Step-by-step explanation:
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.
Answer is
( 7 + 7 ) * ( 7 + 1/7)
= (14) * ( (49 + 1)/7)
= 14 * 50 /5
= 2 * 50
= 100
