if Earth is about 4.6 billion (4.6 X 10^9) years old, how many processional cycles have occurred?

Question

~~~HOW CAN I DO THE MATH? I WANT TO UNDERSTAND IT.

Answer 1

At least 170,000 if we use a period of 27,000 years -- although at the time of earth's formation the Moon was much closer, therefore exerted a stronger tidal pull, which would have increased precession significantly.

Answer 2

Using a cycle of 23,000 years, express all numbers in scientific notation and divide.

4.6 x 10^9 divided by 2.3 x 10^4

First divide the 4.6 by 2.3 which equals 2
Now subtract the exponent 4 from the 9 which equals 5

Now combine: 2.0 x 10 ^ 5
note that you leave the 10 alone

Answer 3

Hi
