I need help with this question not sure how to do

Answer 1

Hello there. To solve this question, we have to remember some properties about radicals.

Given the following radical expression:

`√(16\cdot4)`

We want to determine which is the option that is equal to it.

The first property we can use to determine the answer directly is:

`√(a\cdot b)=√(a)\cdot√(b)`

Hence it is equal to

`√(16\cdot4)=√(16)\cdot√(4)`

You can also notice that, calculating the value, none of the other answers will be correct since
