Answer 1

There are infinite numbers. For example, I'll give you one:

$let \: x = \sqrt[4]{3}$

Then

${x}^{2} = \sqrt[4]{3^{2} } = {3}^{2 \times \frac{1}{4} } = {3}^{ \frac{1}{2} } = \sqrt{3}$

which is an irrational number.

and

${x}^{4} = \sqrt[4]{3 ^{4} } = {3}^{4 \times \frac{1}{4} } = 3$

which is rational number.

4 root 5 whole square
