Question

simplify radical 32??

Answer 1

What is a small(ish) number that can be rooted that fits into that? Like 9,16,25,36.

Answer 2

2 @hawkfalcon

Answer 3

Not 2, that can't be rooted. In this case you would use 16.

Answer 4

For simplifying radicals, find a rootable number that fits into your radical an even amount of times. So, 16.

Answer 5

Then, 32/16 = 2, so you are left with a 2 in the radical, and the root of 16 outside of it.

Answer 6

so the answer is 16 radical 2

Answer 7

No, you have to root the 16, as you moved it outside of the radical. Think of it as \[\sqrt{16} * \sqrt{2} at this point. so \it would be 4\sqrt{2}\]

Answer 8

Does that make sense?

Answer 9

yes thanks
