Question

Which sign makes the statement true?
1.50 x 101 ? 1.50 x 10-1

Answer 1

1.50 * 10^1 is greater than or the first box answer than 1.50 * 10^-1

Explanation:

This is because when a number is to the first power and positive, it remains the same. So the simplified version of 1.50 * 10^1 is 1.50 * 10 which is 15.

Then when multiplying something by a negative number, we turn it into a decimal, so 10^-1 is 1/10. This simplified is 1.50 * 1/10 which is 0.15

So with both answered simplified, we get 15 and 0.15 and of course 15 is more.
