To calculate after how many years 75% of the original amount of Uranium-238 has been depleted, you can use the radioactive decay formula. The formula is: N(t) = N0 * (1/2)^(t/t1/2), where N(t) is the amount of Uranium-238 remaining after time t, N0 is the original amount of Uranium-238, t is the time in years, and t1/2 is the half-life of Uranium-238. By plugging in the values and solving for t, you can determine the number of years it takes for 75% of the original amount to be depleted. **
