A non-zero rational number (10) multiplied by an irrational number (pi) is always irrational.

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.

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.

No because the value of pi as regards to a circle is an irrational number

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.

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.

Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.

Pi is irrational. Irrational numbers, by definition, have no factors.

Johann Lambert proved that pi is irrational in 1761.

pi is an irrational number. It is irrational because it cannot be expressed as a ratio of two integers.

Consider pi and 4 - pi. 4 - pi + pi = 4, which is clearly rational. However, both pi and 4 - pi are irrational, as you can verify. plz to be lerning numburs Then consider pi + pi = 2pi, which is clearly irrational. The sum of two irrational numbers, therefore, may or may not be rational.

There is no "last digit" of pi. Pi is irrational. Irrational numbers go in forever; like infinity

There is no pattern in pi. it is irrational

Johann Lambert proved that pi is irrational in 1761.

Since pi is irrational, any multiple of it is too.

pi is an example of an irrational number.

Yes, it is an irrational number.

It is an irrational number

2 times pi is not an integer. Since Pi is an irrational number, 2 pi is also an irrational number.
