[tex](3\frac{1}{3})^{\frac{1}{2}}[/tex]

Is it rational or irational?

How do you work it out?

[tex]\frac{10}{3}^\frac{1}{2}[/tex]

Your answer should be [tex]\left(\frac{10}{3}\right)^{\frac{1}{2}}[/tex]

Do you think it is rational or irrational?

As you put the denominator as the surd outside thingy (wot ever it's called) and the rest inside the root. On a calculator it gives me 2.108185... which is a real number, and virtually all real numbers are irrational?

P.S How do i tell on a calculator if the number is real or not. It could stop after 50 places, and my calculator only goes to 11
