12 x 14 = 194
12 x 12 + 14 = 158
14 x 14 = 196 13 x 13 = 169 12 x 12 = 144196
A million times a million is a trillion, so 200 trillion. or 200 x 10^12 = 2 x 10^14. You could also do it as 2 x 10^2 x 10^6 x 10^6, add the exponents of ten = 14.
14! = 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11 x 12 x 13 x 14 = 87178291200

There are 2.54 centimetres in one inch. There are 12 inches in one foot. Therefore, 14 feet 10 inches is equal to (14 x 12 x 2.54) + (10 x 2.54) = 452.12 centimetres.
1 billion = 1,000,000,000 or 10^9 1 trillion = 1000 nillion = 1,000,000,000,000 or 10^12 14 trillion = 14,000,000,000,000 or 14 x 10^12
10 x 12 is bigger.
You haven't said what's the total size of the group.Here are all of them:Groups of 2: (12) x (16) = 192Groups of 4: (12 x 11) x (16 x 15) / (2!)2 = 7,920Groups of 6: (12 x 11 x 10) x (16 x 15 x 14) / (3!)2 = 123,200Groups of 8: (12 x 11 x 10 x 9) x (16 x 15 x 14 x 13) / (4!)2 = 900,900Groups of 10: (12 x 11 x 10 x 9 x 8) x (16 x 15 x 14 x 13 x 12) / (5!)2 = 3,459,456Groups of 12: (12 x 11 x 10 x 9 x 8 x 7) x (16 x 15 x 14 x 13 x 12 x 11) / (6!)2 = 7,399,392Groups of 14:(12 x 11 x 10 x 9 x 8 x 7 x 6) x (16 x 15 x 14 x 13 x 12 x 11 x 10) / (7!)2 = 9,060,480Groups of 16:(12 x 11 x 10 x 9 x 8 x 7 x 6 x 5) x (16 x 15 x 14 x 13 x 12 x 11 x 10 x 9) / (8!)2 = 6,370,650Groups of 18:(12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4) x (16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8) / (9!)2 = 2,516,800Groups of 20:(12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3) x (16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7) / (10!)2 = 528,528Groups of 22:(12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2) x(16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6) / (11!)2 = 52,416Groups of 24:(12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) x(16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5) / (12!)2 = 1,820You can't make groups of more than 24, because there are only 12 boys,and the group must have the same numbers of boys and girls.Total number of possible groups of all sizes = 30,421,754You're welcome.
