Question

Can someone please help me with this question?

Answer 1

12

Explanation:

You simplify root 72 as much as possible which would be root 36 times root 2.

This would have then equaled 6 root 2.

You do 6 × root 2 × root 2.

This would then be 6 × 2, which would then equal 12.

Hope this helps :)
