Question

Help I don't understand this, Can someone explain this to me?

Answer 1

5×1,000,000,000

Explanation:

You multiply all of them and whichever gives you the the same number as 5,000,000,000 is the right one which so happens to be 5×1,000,000,000

Answer 2

The second answer is correct (5 x 1,000,000,000)

Explanation:

Just count the number of zeros. Multiplying a number liket his by five doesn't change the number of zeros
