314 ÷ 2 = 157

The square root of 2 is irrational, yet the product of it with itself is 2. So the answer is no.

yes, unless you were to simplify (example: 3 times 3/2 = 6/2 = 3)

No, not evenly. It goes in 52 times with a remainder of 2.

314 x 78 = 24492

The square root of 2 is irrational, yet the product of it with itself is 2. So the answer is no.

Can be irrational or rational.1 [rational] * sqrt(2) [irrational] = sqrt(2) [irrational]0 [rational] * sqrt(2) [irrational] = 0 [rational]

A rational number is a real number which can be expressed as a division of two integers. A real number which is not rational is called irrational. Since 3.14 = 314/100 and 314 & 100 are integers it is a rational number.

No, since Pi is an irrational number, 2(pi) would still be irrational.

No. It can be written as a fraction where the denominator is not 0. For example, 314/100. This makes it rational.

314 x 78 = 24492

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

Not always. For example sqrt(2) and 1/sqrt(2) are both irrational, but their product is the rational number 1.
