Irrational numbers are numbers that cannot be expressed as fractions with whole numbers. They are generally roots (such as the square root of two) or constants (such as pi and… e). They are interesting because they cannot be exactly expressed as decimal numbers because they never terminate or repeat themselves. (MORE)

The product of two irrational numbers may be rational or irrational. For example, sqrt(2) is irrational, and sqrt(2)*sqrt(2) = 2, a rational number. On the other hand, (2^(1/4…)) * (2^(1/4)) = 2^(1/2) = sqrt(2), so here two irrational numbers multiply to give an irrational number. (MORE)

Any number that can be completely written down with digits is rational. You appear to have succeeded in writing down the number you're asking about, so it's a rational nu…mber. (MORE)

No. An irrational number can only be part of a whole number. Every whole number is rational. 1000000

Sometimes it is and sometimes it isn't. The square root of 2 and the square root of 3 are both irrational, as is their product, the square root of 6. The square root of 2 and …the square root of 8 are both irrational, but their product, the square root of 16, is rational (in fact, it equals 4). (MORE)

An irrational number is a real number that cannot be expressed as a ratio of two integers. In decimal terms, it is a real number that has either a terminating decimal or an i…nfinitely recurring decimal. This would apply whatever the integer base, such as binary, octal, hexadecimal. (MORE)

Yes, but not always. An easy example is sqrt(2) + sqrt(2) + sqrt(2) = 3sqrt(2), an irrational number. An easy counterexample is 2sqrt(2) + -sqrt(2) + -sqrt(2) = 0, w…hich is rational. (MORE)

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4 20c + 5 = 5c …+65 20c - 5c= 65 - 5.
15c = 60.
15c/15 = 60/15.
c = 4 (alternative method). (MORE)

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

No, because if need be it can be expressed as a fraction whereas irrational numbers can't be expressed as fractions.
