Answer:

A √40

Explanation:

The given radical expression can be written as ...


\displaystyle 2√(n+4)=√(2^2)\cdot√(n+4)=√(4(n+4))=√(4n+16)

The last two versions of this expression tell you two things:

  • the value under the radical must be a multiple of 4
  • the value under the radical is greater than 16

Only one answer choice meets these requirements:

√40
