Question

Please choose the best answer that describes the scientific notation for 3,134,000,000

Answer 1

To do scientific notation of 3,134,000,000 we need to move teh decimal places to the left till we get a number between 1 and 10.

3,134,000,000

Move the decimal 9 places to the left to get : 3.134

Now, since we moved it 9 places to the left, we need to multiply it. 

3.134 × 10^9 
The exponent is positive because we moved it to the left.

Final answer: 3.134 × 10^9

Answer 2

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
♥ 313.4000000
♥ 31.34000000
♥ 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.
