The half-life of uranium-235 is 700,000,000 years. The half-life of uranium-238 is 4.463 × 10^11 years longer. What is the half-life of uranium-238? The answer should be in decimal form.

To find the half-life of uranium-238, we need to add the additional 4.463 × 10^11 years to the half-life of uranium-235.

Half-life of uranium-235 = 700,000,000 years
Additional half-life of uranium-238 = 4.463 × 10^11 years

Total half-life of uranium-238 = Half-life of uranium-235 + Additional half-life of uranium-238
Total half-life of uranium-238 = 700,000,000 + 4.463 × 10^11

Total half-life of uranium-238 ≈ 4.463 × 10^11 years (in decimal form)
