No.
Yes. Irrational numbers are found by getting the square root of a negative number.
It is impossible to have a surd that is not irrational. Surds are defined to be an irrational number (square root of a number).
An irrational number is one that cannot be expressed as a ratio of two integers.
No. A "rational" number is one that can be expressed as a "ratio" - a fraction. An IRRATIONAL number is one that cannot be expressed as a fraction.
No.
Yes. Irrational numbers are found by getting the square root of a negative number.
Provided that the rational number is not 0, the product is irrational.
At least one of the factors has to be irrational.* An irrational number times ANY number (except zero) is irrational. * The product of two irrational numbers can be either rational or irrational.
An irrational number is one which cannot be expressed as a ratio of two integers.
An irrational number is a real number that is not rational. A rational number is one that can be expressed as a ratio of two integers. An irrational number cannot be expressed in this way.
It is impossible to have a surd that is not irrational. Surds are defined to be an irrational number (square root of a number).
An irrational number is one that cannot be expressed as a ratio of two integers.
Not always. For example sqrt(2) and 1/sqrt(2) are both irrational, but their product is the rational number 1.
No. A "rational" number is one that can be expressed as a "ratio" - a fraction. An IRRATIONAL number is one that cannot be expressed as a fraction.
5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!
An irrational number.
