Any number that can't be expressed as a fraction is an irrational number.
I don't knw all the possible numbers, but π is an example. π2 is irrational such as π.
No. Perfect squares as the squares of the integers, whereas irrational squares as the squares of irrational numbers, but some irrational numbers squared are whole numbers, eg √2 (an irrational number) squared is a whole number.
81 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
All rational and irrational numbers are real numbers.
No because 36 squared is 1296 which can be expressed as an improper fraction in the form of 1296/1 whereas irrational numbers can't be expressed as fractions.
All irrational numbers are not rational.
All irrational numbers are real, but not all real numbers are irrational.
12 squared is not irrational. It's 144 .
No. All irrational numbers are real, not all real numbers are irrational.
Ye it is true that all irrational numbers are real numbers that can't be expressed as fractions.
Quite the opposite. All natural numbers are rational. None of them are irrational.
There are no two whole numbers which when squared sum to 62. There are infinitely may pairs of irrational numbers that when squared sum to 62, eg 1 and √61, 2 and √58
