Sure; for example, 10 + pi is irrational, 10 - pi is irrational. Both are positive. If you add them, you get 20.
Yes. For example: a = 10 - pi b = pi Both are irrational; the sum a + b is 10.
No because the value of pi as regards to a circle is an irrational number
It is irrational, just like pi
If a numerator and/or denominator in a fraction is irrational, the entire fraction is irrational. Since pi is irrational, pi divided by two is also irrational.
Pi, is an irrational number (it cannot be written as a fraction) For this reason, 3 times pi is also irrational.
It can. pi / sqrt(5) = an irrational number. However, it doesn't have to be: pi / pi = 1.
The square of pi is an irrational number.
It is irrational
The product of two rational numbers, as in this example, is always RATIONAL.However, if you mean 10 x pi, pi is irrational; the product of a rational and an irrational number is ALWAYS IRRATIONAL, except for the special case in which the rational number is zero.
No, since Pi is an irrational number, 2(pi) would still be irrational.
