Question

Which of the following expressions is equivalent to 4,325,000,000

Answer 1

For this case we must find an expression equivalent to:

`4,325,000,000`

To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.

We test each option.

Option A:

`4,325 * 10^(-9)`

If we run the decimal 9 spaces to the left we have:

`0.000000004325`

Option B:

We discard it because the exponent is negative.

Option C:

`4,325 * 10 ^ 6`

We run the decimal 6 spaces to the right

`4,325,000`

Option D:

`4,325 * 10 ^ 9`

We run the decimal 9 spaces to the right

`4,325,000,000`

Answer:

Option D
