Bubbly:

A or D, i'm thinking?Which one is an irrational number? * square root of 16 6 squared 18 12.5 square root of 12

Gdeinward:

What brought you to this conclusion?

Bubbly:

because the other answers are rational, and 6 and 12 squared are decimals

Gdeinward:

the last option is saying the square root of 12. Is the square root of 12 rational?

Bubbly:

no, I don't think so

Gdeinward:

your right, the square root of 12 isnt a perfect square, so it is irrational

Bubbly:

Oh wow, that was easier than I thought it was, thank you so much.
