I really like this lovely radicals task from Terry Stickels. It simply asks: Which of the following is the smallest?

I shared it on twitter, and I loved reading through people’s logical reasoning as they worked through the problem!

I found this problem in The Big Book of Mind-Bending Puzzles by Terry Stickels.
