Yes his reasoning is correct because you can not cut a person in half. you can not be born with half of a body so you would have to round your result to the nearest whole number which in this case is 2 so he would technically be correct

Hey there!!

We have:

... 3²· 3ⁿ = 3²⁰

Remember the exponent rule:

When the bases are equal and the terms are multiplied, then we add up the exponent.

mⁿ · mˣ = mˣ⁺ⁿ

Hence, this equation would result as :

... 3²⁺ⁿ = 3²⁰

... 2+n=20

... n=18

Hence, the required answer is 18.
