2^21=2,097,152
(27)3 = (2)21 = 2,097,152
21/2 = √2 ≈ 1.414 The rules of indices are that when multiplying add them. 21/2 x 21/2 = 21/2 + 1/2 = 21 = 2 So multiplying 21/2 by itself gives 2. But what number multiplied by itself gives 2? The answer is the square root of 2. Thus 21/2 is the square root of 2.
^ means "to the power of" F ^ 2 + 4 = 5 ^ 2 F ^2 +4 = 25 F ^2+4 -4 = 25 -4 F^2 = 21 F = (square root of 21)

21/2 = √2 ≈ 1.414 The rules of indices are that when multiplying add them. 21/2 x 21/2 = 21/2 + 1/2 = 21 = 2 So multiplying 21/2 by itself gives 2. But what number multiplied by itself gives 2? The answer is the square root of 2. Thus 21/2 is the square root of 2.
2-1 = 1/(21) = 1/2 = 0.5

I use the ^ symbol to mean 'to the power of' and * to mean multiply. You want to find i^21 Remember i^4 = i^2 * i^2 = -1 * -1 = 1 So i^21 = i^4 * i^4 * i^4 * i^4 * i^4 * i^1 = 1 * 1 * 1 * 1 * 1 * i = i.
2.0*1021 is 2 sextillion.
21 to the 2nd power is 441.
