11,463,000,000
The correct answer is:
447,000,000,000
To find the half-life of uranium-238, we need to add 4.463×10^11 years to the half-life of uranium-235, which is 700,000,000 years.
Adding these two values together, 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.
To find the half-life of uranium-238, you need to know that it is 4.463×10^11 years longer than the half-life of uranium-235.
To calculate the half-life of uranium-238, you can add the difference in half-lives to the known half-life of uranium-235.
So, the calculation would be:
Half-life of uranium-238 = Half-life of uranium-235 + 4.463×10^11 years
Substituting the value of the half-life of uranium-235 (700,000,000 years) into the equation:
Half-life of uranium-238 = 700,000,000 years + 4.463×10^11 years
Calculating the sum:
Half-life of uranium-238 ≈ 516,300,000,000 years
Therefore, the correct answer is 516,300,000,000.
The answer should be in decimal form.
My apologies for the confusion. To express the answer in decimal form, we can write it as:
516,300,000,000 years = 5.163 × 10^11 years
Therefore, the correct answer in decimal form is 5.163 × 10^11 years.
What about 4.4637*10^11
I apologize for the previous incorrect response. You are correct, to express the answer in decimal form, the correct value is:
4.4637 * 10^11 years
Therefore, the correct answer in decimal form is 4.4637 * 10^11 years.
