The square root of any positive, non-square number will be both real and irrational.
All real numbers are irrational. For example, Pi is an irrational number that is a real number. Other irrational numbers can be the square root of an imperfect square.
Every irrational number is a real number.
No. All irrational numbers are real, not all real numbers are irrational.
No. The square root of negative one is an example of an imaginary (not real) number. Pi is irrational, but real.
No, because it could be a rational number.

No. All irrational numbers are real, not all real numbers are irrational.
All irrational numbers are Real numbers - it's part of the definition of an irrational number. Imaginary numbers are neither rational nor irrational. An example of a number that is both Real and irrational is the square root of two. Another example is the number pi.
No. The square root of negative one is an example of an imaginary (not real) number. Pi is irrational, but real.
There can be no such number.
Yes.
No, a real number could also be a rational number, an integer, a whole number, or a natural number. Irrational numbers fall into the same category of real numbers, but every real number is not an irrational number.
Euler's number, e = approx 2.71828
No, because it could be a rational number.
A rational number cannot also be irrational. A real number is either rational, or it is irrational.
Since pi is an irrational number, then 3pi will be an irrational also.
