Question

Which of the following expressions cannot be written as an integer?

-3^0
18/3
1.2 x 10^-2
49

Answer 1

1.2 x 10^4

Explanation:

Answer 2

1.2*10^-2

Explanation:

-3^0 is 1, because anything to the power of 0 (except for 0) is always equal to 1. 1 is an integer, so this is not the answer.

18/3=6, and 6 is an integer, so this is not the answer either.

1.2*10^-2 = 1.2*0.01 = 0.012, which is not an integer, so this is the answer.

49 is an integer, so this is not the answer:

Therefore, the answer to this problem is 1.2*10^-2
