Answer 3

but \(\large \sqrt{2}\) is an irrational number

so is \(\large 10\sqrt{2}\)

Answer 4

\(\large \sqrt{8}\) is an irrational number, and so is \(\large 4+\sqrt{8}\)

Answer 5

0.63 is rational since 0.63 = 63/100

\(\large \sqrt{196} = 14\), so that's a rational number

that's irrational, but so is \(\large 10\sqrt{2}\)

Answer 9

are there any exponents over the \(\large 10\sqrt{2}\)
