Is there any point in this question - apart from a pointless exercise in multiplication? The entire life span of the solar system is far less than that. In around one hundredth of the period the earth will cease to exist. No earth means nothing to orbit the sun in a year: so no year! In the meantime, the earth's orbit is slowing down so a year in 1000000 years' time will be many more seconds longer than it is now.
But, pontless though it is, the question was asked so the answer is approx 315576000000000000000 seconds.
About 1,009,843,200 seconds in 32 years.
20 years = 631,138,519 seconds.
25 years = 788,923,149 seconds.
10 years = 315,569,260 seconds.
13 years = 410,240,038 seconds.
10000000000000
3% of 10000000000000 = 3% * 10000000000000 = 0.03 * 10000000000000 = 300,000,000,000
10000000000000 = 10,000,000,000,000
1/3 every two years
The number 10000000000000 can be expressed as 10^13 in exponential form. This is because each additional zero in a number represents a power of 10. In this case, there are 13 zeros, so the number can be written as 10 raised to the power of 13.
4-10000000000000 = -9999999999996
10000000000000-3747577 = 9999996252423
16 years = 504,910,816 seconds.
There are 1,452,576,000 seconds in 46 years.
10000000000000
100 + 10000000000000 = 10000000000100
There are 1,358,724,800 seconds in 43 years.
