The half-life of uranium-235 is 700,000,000 years The half-life of uranium-238 is 4.463 * 10 ^ 11 years longerWhat the half-life of uranium-238? the  answer should be in decimal form point)

The half-life of uranium-238 is 4.463 × 10^11 years (446,300,000,000 years).

To calculate the half-life of uranium-238 in decimal form, we need to express the given value in scientific notation.

The half-life of uranium-238 is 4.463 * 10^11 years.

In decimal form, this would be:

446,300,000,000 years

The half-life of uranium-238 is longer than that of uranium-235 by a factor of 4.463 * 10^11 years.

So, the half-life of uranium-238 would be:

700,000,000 years + 4.463 * 10^11 years = 446,300,000,000 years

In decimal form, the half-life of uranium-238 is approximately 4.4633 * 10^11 years.
