Answer 1

Answer: 6√2

Explanation:

8 × 9 is 72.

8 can be simplied to 4 × 2.

And 4 can be simplified to 2 × 2.

So far there are three 2s and a 9.

9 can be simplified down to 3 × 3.

Theres a pair of 2s and a pair of 3s, so you multiply 2 × 3 and thats 6 so you put 6 on the outside of the radical. Theres one 2 leftover from all the simplifying so that goes inside the radical to give you 6√2
