To find the half-life of uranium-238, we add the additional time to the half-life of uranium-235.
The half-life of uranium-238 is 700,000,000 + 4.463×1011 years = 4.4637×1011 years.
So the correct answer is 4.4637×1011.
To find the half-life of uranium-238, we need to add the length of time by which it is longer than the half-life of uranium-235.
Given:
Half-life of uranium-235: 700,000,000 years
Difference in half-lives: 4.463×10^11 years
Adding the difference to the half-life of uranium-235:
700,000,000 + 4.463×10^11 = 4.4637×10^11
Therefore, the half-life of uranium-238 is 4.4637×10^11 years.
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.
The half-life of uranium-235 is given as 700,000,000 years.
So, to calculate the half-life of uranium-238, we can add 4.463×10^11 years to 700,000,000 years.
700,000,000 + 4.463×10^11 = 447,000,000,000
Therefore, the half-life of uranium-238 is 447,000,000,000 years.
So, the correct answer is 447,000,000,000 in decimal form.
