Question

If I'm simplifying 2a^0, what does the zero do? I've never seen that before and I'm confused ):

Answer 1

a^0 = 1

(except if a is 0)

Answer 2

so would the answer be 3?

Answer 3

2*1 is not 3

Answer 4

nvm, my answer choices are 2a

0

2

1

Answer 5

so 2a?

Answer 6

no 2a^1 is 2a
2a^0 is 2*1

what is 2 times 1?

Answer 7

if you are wondering why a^0 is 1, it "fits a pattern"

1/a is a^(-1)
a is a^1
multiply a^-1 * a^1 we add exponents to get a^0
but we know 1/a * a = 1
so a^0 must be 1

Answer 8

so the answer is just 2?

Answer 9

I just don't understand where the A would go then...
