Find four irrationals

Question: Find four irrational numbers between 3 and 4

My attempt (thanks to Pero and Agentredlum):

3^2 = 9 and 4^2 = 16
So the square root of non-perfect squares from 9 to 16 such as 10, 11, 12, 13, 14, 15 should be irrational
So the answer is

Am I correct? Is there another way?

Re: Find four irrationals

You could also use any rational number, between 9 and 16, which is not a square.
