The rule would be : 3^x, where x starts at 0.

3^0 is 1,

3^1 is 3, because 3 one time is 3.

3^2 is 9, because 3x3 is 9.

3^3 is 27, because 3x3x3 is 27

Answer: 3^x

Where the angle bisectors intersect determines the center of the incircle.
Where the side perpendicular bisectors intersect determines the center of the center of the circumcircle. From these definitions, you should be able to determine the points you want.

Aneli [31]

Just invert it like:
$7*13=91 \\ 13*7=91$

There you have your common denominator! Don't forget to multiply the numerator as well.
