1 followed by 21 zeros or 1 sextillion.
1000000000000000000000 It is 10 with 21 zeroes.
10^21 = 1,000,000,000,000,000,000,000
no 9 + 10 = 19 11 + 10 = 21 9 + 12 = 21
No, 10 plus 9 cannot equal 21. The correct sum of 10 and 9 is 19. The statement that 10 plus 9 equals 21 is mathematically incorrect.
10 to the - 31st power = -21
two fractions equal to 10.5 = 21/210.5 * 10/10 = 105/10 or 21/2 in fraction in lowest term
21
There are 10 millimetres in one centimetre. Therefore, 21 centimetres is equal to 21 x 10 = 210 millimetres.

Oh honey, 10 to the negative 21 power is just a teeny tiny number. It's equal to 0.000000000000000000001. So basically, it's a whole lot of zeros before you finally hit that 1 at the end. Hope that clears things up for ya!
