Not always. For example sqrt(2) and 1/sqrt(2) are both irrational, but their product is the rational number 1.
Yes
The square root of 84 is irrational and is approx 9.1652.
That simply isn't true. The sum of two irrational numbers CAN BE rational, but it can also be irrational. As an example, the square root of 2 plus the square root of 2 is irrational.
Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]
No. 0.9 is rational. It is equal to 9/10.
No. If the rational number is not zero, then such a product is irrational.
The product of 0 and an irrational is 0 (a rational), the product of a non-zero rational and any irrational is always irrational.
Since pi is irrational, its product with any other number is also irrational. The only exception is a multiple of its own reciprocal.
No.
Yes, it will always be irrational.
Yes
The sum is irrational.
Yes, always.
The square root of 84 is irrational and is approx 9.1652.
The circumference of a circle divided by its diameter is equal to pi which is an irrational number.
Not necessarily. 0 times any irrational number is 0 - which is rational.
An irrational number is a number that has no definite end. So it can't be multiplied or divided by anything to make a rational number that does have a definite end.
