2013 Power of 3+2012 power of 3+2011 power of 3+…… How much is +3+1 to the second power of +3? What do you say?

The first item is 1, the common ratio is 3, and the number of items is 2014.
3^0+3^13^2+3^3+…… +3^2013=3^0*(1-3^2014)/1-3=(3^2014-1)/2

Calculation:1+2/3+3/3 square +4/3 cube +5/3 4th power +.+101/3 100th power

Write the sum as s100, s100=1+2/3+3/3^2+.101/3^100, s100/3=1/3+2/3^2+3/3^3+.100/3^100+101/3^101, s100-s100/3=2s100/3=1+1/3+1/32+.1/3^100-101/3^101=(3-(1/3)^100)/2-101/3^101, s100=9-(1/3)^99/4-101/2x3^100.
