The result of 9 ∙ 10-⁵ divided by 3 ∙ 10-⁹ is 3 × 10⁴. Details about exponential functions can be found below.
<h3>How to calculate multiplication involving exponentiation?</h3>
Exponentiation is the process of calculating a power by multiplying together a number of equal factors, where the exponent specifies the number of factors to multiply.
According to this question, the following exponential function is given:
9 × 10-⁵ ÷ 3 × 10-⁹
9/3 × 10-⁵+⁹
3 × 10⁴
Therefore, the result of 9 ∙ 10-⁵ divided by 3 ∙ 10-⁹ is 3 × 10⁴.

The nucleus that completes the equation given above is 218/85 At, which is option D.
<h3>What is a nuclear fission?</h3>
Nuclear fission is a nuclear reaction in which a large nucleus splits into smaller ones with the simultaneous release of energy.
According to this question, the following nuclear fission reaction is given: 222/87Fr = 4/2He+ ?
To find the missing nucleus, we subtract 4 from 222 to get 218, therefore, the nucleus that completes the equation given above is 218/85 At.
