What is 3,700,000 in scientific notation??
lawyer [7]
<h3>Answer:    Choice D)  3.7 * 10^6</h3>

=========================================================

Explanation:

Place a decimal point between the first two digits 3 and 7.

Now ask yourself how you can go from 3.7 back to the original value. Notice we can move the decimal point 6 spots to the right to go from 3.7 back to 3,700,000

Therefore, the exponent over the 10 is 6. The exponent is positive to mean we move the decimal point to the right. If we had a negative exponent, then we'd move left.

You can use a calculator to confirm that 3.7 * 10^6 = 3,700,000

--------------

Side notes:

3,700,000 = 3 million, 7 hundred thousand

3,700,000 = 3.7 million
