To find the half-life of uranium-238, we need to add the additional time to the half-life of uranium-235.
Half-life of uranium-235: 700,000,000 years
Additional time for uranium-238: 4.463×1011 years
Adding these two values together: 700,000,000 + 4.463×1011 = 4.4637×1011 years
Therefore, the half-life of uranium-238 is 4.4637×1011 years.
