Question

Can someone help me work this question out?

The area of Greenland is 840,000 square miles. What is this number in scientific notation?

Answer 1

place a decimal point so that the number is between 1 and 10
Count the digits from there to the end.

840000 = 8.4 x 10^5

if counting to the left, use negative powers.

0.00034 = 3.4 x 10^-4

Answer 2

ITs
1. 8.4*10^5
2. 9.16*10^-6
3. 5,750,000,000
4. 0.00068
5. 520,000,000
