Mars- 6.8×10to the 3rd power Earth- 1.2763×10 to the 4th power
10 to the 4th power looks like: 10,000
10 to the 3rd power looks like: 1,000
Now that you have that just multiply the powers by the number.
Mars: 6.8× 1,000= ← equation
Earth: 1.2763× 10,000= ← equation
an easy way to remember the powers of 10 are just adding a 0 for every power of 10. example, 10 to the power of 1 is 10, 10 to the power of 2 is 100. Or you can multiply 10 by itself that many times. example 10 to the power of 4: 10×10×10×10= 10,000.
With decimals you can move the decimal that many times. example, 678.90. if 678.90 is moved 10 to the power of 3 than you can move the decimal to the right 3 times and get 678,900 because you have to add another 0 because its the power of 3 and not 2 it it was by 2 it would have been 67,890.
Earth answer: 12,763 Mars answer: 6,800 Earth is greater by: 5,963
