20 = 1
Consider what is the value of 2a ÷ 2a? Any number divided by itself is 1. Thus:
2a ÷ 2a = 1
The law of indices says that when dividing, they are subtracted, for example:
25 ÷ 22 = (2 x 2 x 2 x 2 x 2) ÷ (2 x 2) = 2 x 2 x 2 = 23 = 25-2
So 2a ÷ 2a is (also):
2a ÷ 2a = 2a-a = 20
Since any number subtracted from itself is 0 (= a - a). This must have the same value as before, thus:
20 = 1
The 2 above can be replaced by any number x which means that any number to the power 0 is 1:
x0 = 1

Give a one-line C expression to test whether a number is a power of 2?
The one line expression is: ((0 != n) && !(n & n-1)) example: int main () { for (int n = 0; n <= 1000001; ++n) { if ((0 != n) && !(n & n-1)) cout << n << " is a power of 2" << endl; } return 0; } will produce: 1 is a power of 2 2 is a power of 2 4 is a power of 2 8 is a power of 2 16 is a power of 2 32 is a power of 2 64 is a power of 2 128 is a power of 2 256 is a power of 2 512 is a power of 2 1024 is a power of 2 2048 is a power of 2 4096 is a power of 2 8192 is a power of 2 16384 is a power of 2 32768 is a power of 2 65536 is a power of 2 131072 is a power of 2 262144 is a power of 2 524288 is a power of 2
