The product of 0 and an irrational is 0 (a rational), the product of a non-zero rational and any irrational is always irrational.
No.A rational times an irrational is never rational. It is always irrational.
Unless the rational number is zero, the answer is irrational.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
Not necessarily. 0 times any irrational number is 0 - which is rational.
Actually the product of a nonzero rational number and another rational number will always be rational.The product of a nonzero rational number and an IRrational number will always be irrational. (You have to include the "nonzero" caveat because zero times an irrational number is zero, which is rational)
Not always. For example sqrt(2) and 1/sqrt(2) are both irrational, but their product is the rational number 1.
75 times 75 = 5625 which is a rational number
It the radius is r then the area is pi*r*r - which is pi times a rational number. pi is an irrational number, so the multiple of pi and a rational number is irrational.
No; since pi is irrational if you multiply it by a rational number it is still irrational
Well, (pi) x (1/pi) = 1 .
No because 15 times pi is an irrational number
