MULTIPLE CHOICE QUESTION

Carlo was simplifying the expression  32n4k7\sqrt{32n^4k^7}  on his homework.  He recorded his answer as 16 n2k32kn^2k^3\sqrt{2k}  .  What mistake did Carlo make in simplifying?  

Carlo did not make a mistake.

He should have taken the square root of 16 instead of writing 16.

He should have recorded the exponent on the variable k as 4 instead of 3.

He should not have written he  k3k^3  on the outside and instead left it as  k7k^7  under the radical symbol.
