2*(4*3 - 1)
20 + [(21+23)/22]2 = 20 + [44/22]2 = 20 + 22 = 20 + 4 = 24
22, 28, 82 and 88.
We can get 29 by using their squares like: (42 + 32 + 22) / 1 = 29
71 - 49
only once
only 1, 2, 11, and 22
The only composite number that is a factor of 22 is 22 itself.
There are 22 sums, if you don't include a number more than once. Where did you here a question like that?
12 = 1 22 = 1 + 3 32 = 1 + 3 + 5 and so on. The square of the nth whole number is the sum of the first n odd numbers.
(22/4)x8-20=24
(23-21) x 22-20
22 x 32 = 36
