Question

You are writing a research paper on plant cells. You got 48,600,000 results on the online search. How do you write 48,600,000 in scientific notation?

Answer 1

Place a decimal point between the first two digits (4 and 8). Erase the commas and the 0s. So you'll have 4.86 left over after you've done that erasing.

Now ask yourself: "how many places to the right must I move the decimal to get 4.86 to turn back to 48,600,000?"

That would be 7 places to the right. That 7 is the exponent over the 10

Therefore, the answer is 4.86 * 10^7

This number is 48.6 million
