2x2x2x2 or 2 to the power 4
4
Itself
8 to the power (2/3) equals 4.
Since 2^2=4 ........1 and 2*0=0 ..........2 Dividing both sides of equation 1 by 2^2 2^2/2^2=4/2^2 => 2^(2-2)=4/4 or 2^0=1 (QED)

2 to the second power, or (2^2), equals 4. Similarly, 1 to the second power, or (1^2), equals 1. Therefore, (2^2 = 4) and (1^2 = 1).
It would be 4 because 2 to the second power is really 2 * 2, which equals 4.
(-2)^2 = -2 * -2 = 4.
