Answer:
10^20
Step-by-step explanation:
So in this word problem, we have to multiply 10^13 bacteria cells on a single person by the 10^7 of people.
Always remember this, when you have exponenets with the same bases, and the question asks for multiplying and dividing exponents, you just need to add and subtract the exponent.
So in this case, we will just add since it calls for multipactation.
So we need to solve:
10^13+7
This will just equal:
<u>10^20 power</u>
Hope this helps ;)
There should be a typo in the question: the correct formula would be

Let's compute
first. We have

If we intersect this set with X, we have

So, that would be the left hand side. For the right hand side, we have

And their union is again
