asked • 01/15/18

can you help me with math I don't understand that.

It follows from Kepler's Third Law of planetary motion that the average distance from a planet to the sun (in meters)

where M = 1.99 × 1030 kg is the mass of the sun, G = 6.67 × 10−11 N · m2/kg2 is the gravitational constant, and T is the period of the planet's orbit (in seconds). Use the fact that the period of the earth's orbit is about 365.25 days to find the distance from the earth to the sun. (Round your answer to one decimal place.)

I already showed you the way.  All you have to do is plug in the numbers and get the final result with your scientific calculator.

The down-vote cast against this answer is frivolous and unjustified.  The equation is correct and the numbers provided for substitution into the equation are correct.  You can plug in the numbers, get the result, and then look up the correct value for the sun-earth distance and see that this is correct.
