How to calculate the inflation rate Assuming that the annual CPI is 3%, how much is the 8W after 35 years compared with the present?

The first year is CPI 1, so the inflation rate of 1 yuan-3% in the first year is equivalent to 1 * (100 + 3) ^ 34 in the second year and 1 * (100 + 3) ^ 34 in the 35th year;
If the first year is 1 * (100 + 3)%, then the 35th year is 1 * (100 + 3) ^ 35;
You can change "1" in the above two formulas to x, and the right side of the equal sign is 8W
