9. Classify the following numbers as rational or irrational according to their type:
√23 = 4.79583152331…
Since the number is non-terminating non-recurring, not perfect square.Hence, it is an irrational number.
√225 = 15 = 15/1
Since the number can be represented in p/q form, and it perfect square. Hence, it is a rational number.
Since the number,0.3796, is terminating, and perfect square. Hence it is a rational number.
The number,7.478478, is non-terminating but recurring. Hence, it is a rational number.
Since the number,1.101001000100001…, is non-terminating non-repeating (non-recurring). Hence, it is an irrational number.
