To find the half-life of uranium-238, we need to add the additional years to the half-life of uranium-235. Adding the given value of 4.463×10^11 years longer to the half-life of uranium-235 (700,000,000 years), we get:
700,000,000 + 4.463×10^11 = 447,000,000,000
Therefore, the half-life of uranium-238 is 447,000,000,000 years in decimal form.
