Question

What is 2 to the negitive one power

Answer 1

(2)^-1
0.5
When it’s a negative you just take the reciprocal.
So 2^1 = 2
But since it’s negative 1 the reciprocal of 2 is 1/2 hence why the answer is 0.5 in decimal form

Answer 2

1/2

Explanation:

2^ -1

We know that a^-b = 1/a^b

1 / 2^1

1/2
