Number Formation Puzzles

Combine the three numbers in each group to get the same result in each of the three groups. You can use addition, subtraction, multiplication, division, and exponentiation. Here's an example of a solved puzzle:

Group 1:	15, 19, 24
Group 2:	11, 30, 36
Group 3:	20, 22, 36

Group 1:	24 / (19 - 15) = 6
Group 2:	(30 + 36) / 11 = 6
Group 3:	20 + 22 - 36 = 6
