Question

Which of the following is the same as 8.4x10²

Answer 1

840

Explanation:

8.4x10^2

8.4x100

move the decimal to the right for the amount of zeros :)

840

Answer 2

For this case we must find an expression equivalent to:

`8.4 * 10 ^ 2 =\\8.4 * 100 =`

We must run the decimal two spaces to the right, then:

`8.4 * 100 =\\840`

If we run a space on the right we have 84, so when running two spaces on the right we have: 840

Thus, 8400 is an expression equivalent to
`8.4 * 10 ^ 2`

Answer:

840
