To find the half-life of uranium-238, we need to add the additional 4.163 × 10^11 years to the half-life of uranium-235.
The half-life of uranium-235 is 700,000,000 years.
The half-life of uranium-238 is 700,000,000 + 4.163 × 10^11 years.
Performing the calculation:
700,000,000 + 4.163 × 10^11 = 416,300,000,000 years.
Therefore, the half-life of uranium-238 is 416,300,000,000 years in decimal form.
To find the half-life of uranium-238, we need to add the additional time to the half-life of uranium-235.
The half-life of uranium-235 is 700,000,000 years, and the half-life of uranium-238 is 4.163 × 10^11 years longer.
To find the half-life of uranium-238, we add the two values:
700,000,000 + 4.163 × 10^11 = 516,300,000,000
Therefore, the half-life of uranium-238 is 516,300,000,000 years. The answer is 516,300,000,000.
To find the half-life of uranium-238, we first need to determine the difference in half-lives between uranium-238 and uranium-235.
Given that the half-life of uranium-235 is 700,000,000 years and that the half-life of uranium-238 is 4.163 × 10^11 years longer, we can calculate the half-life of uranium-238 as follows:
Half-life of Uranium-238 = Half-life of Uranium-235 + Difference in Half-lives
Half-life of Uranium-238 = 700,000,000 years + 4.163 × 10^11 years
Now we can add these two values to find the half-life of uranium-238:
Half-life of Uranium-238 = 700,000,000 years + 416,300,000,000 years
Simplifying the calculation, we get:
Half-life of Uranium-238 = 416,300,000,000 years
Therefore, the half-life of Uranium-238 is 416,300,000,000 years, which corresponds to option "516,300,000,000" in decimal form.
