2 to the power 0 or 20 is equal to 1
To rewrite the number 1 as 2 to a power, you would need to express it as 2^0. In exponential form, any number raised to the power of 0 is equal to 1. Therefore, 1 can be rewritten as 2^0.
(-2)0 = 1
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)
