Answer: last option.
Step-by-step explanation:
According to the Product of powers property, you have:

As you can see, when you can add the exponents when you have powers with equal base.
Then,
and
do not have the same base, therefore, the exponents can't be added.
Therefore, Eli is incorrect, because he added the exponents even though the bases are not the same.
150 because
45/x=30/100 =
30x=4500
divide both by 30
and x=150
