Answer 1

To get 3,134,000,000 in scientific notation we need to move the decimal so we can make the number anywhere from 1 to 10. Lets move the decimal:-

♥ 3134000000.
♥ 313400000.0
♥ 31340000.00
♥ 3134000.000
♥ 313400.0000
♥ 31340.00000
♥ 3134.000000

♥ 3.134000000

So our new number between 1 and 10 is 3.134. We moved the decimal 9 times places to the left. We need to put it in multiplication from with an exponent to get the scientific notion:-

Our exponent will be positive since we moved it left and not right.

♥ 3.134 × 10^9.

☺ Check our work:-

♥ 3.134 × 10^9 = ?
♥ 3.134 × 10^9 = 3134000000
♥ So, we are right!!

☺ So, our scientific notion form is:-

♥ 3.134 × 10^9.
