Answer:
[tex]2^{3}[/tex]
Step-by-step explanation:
2 = [tex]2^{1}[/tex]
2*2 = [tex]2^{2}[/tex]
2*2*2 = [tex]2^{3}[/tex]
For each time you multiply by 2 you add 1 to the exponent.
Does it work backwards? Yes, yes it does..
[tex]2^{3} / 2 =2^{2}[/tex] or if you expand the expressions 8 / 2 = 4.
But wait what is [tex]2^{0} , 2^{-1}, 2^{-2}[/tex] then?
Those numbers represent 1, 1/2 and 1/4 respectively.
