Why is phi an irrational number?
phi = [1+sqrt(5)]/2 sqrt(5) is irrational and so phi is irrational.
Is the square root of 125 an irrational number?
Yes, the square root of 125 is an irrational number. It can be simplified to ( 5\sqrt{5} ), where ( \sqrt{5} ) is an irrational number. Since the product of a rational number (5) and an irrational number ((\sqrt{5})) is irrational, ( \sqrt{125} ) is also irrational.
What is an irrational number between 5 and 7?
4*sqrt(2) Rational multiples of irrational numbers are irrational. sqrt(2) is about 1.414, and 5/4 = 1.25 < 1.414... < 1.75 = 7/4 so 4*sqrt(2) is between 5 and 7, and is irrational.
Is the square of an irrational number rational?
Sometimes. eg the irrational number √2 squared is 2 which is rational (2 = 2/1) eg the irrational number √(√2) squared is √2 which is irrational.
Is 3 times the square root of 2 divided by 5 times the square root of 2 an irrational number why or why not?
I would answer no because 3√2 ____ 5√2 Would simplify to 3 divided by 5 and that is not irrational.
How can be the product of 2 irrational numbers a rational numbers 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!5*sqrt(2) is one irrational number. 1/sqrt(2) is another irrational number.Their product is 5!
Why is phi an irrational number?
phi = [1+sqrt(5)]/2 sqrt(5) is irrational and so phi is irrational.
Is 5.4 an irrational or rational number?
5.4 = 5 2/5 = 27/5 so it is a rational number.
Is 5 irrational number?
5 isn't a irrational number.
Is the square root of 125 an irrational number?
Yes, the square root of 125 is an irrational number. It can be simplified to ( 5\sqrt{5} ), where ( \sqrt{5} ) is an irrational number. Since the product of a rational number (5) and an irrational number ((\sqrt{5})) is irrational, ( \sqrt{125} ) is also irrational.
Is a percent number an irrational number?
A percent can be represented as a fraction of x/100, and so is not irrational, unless the numerator of the fraction (the # before the %) is itself irrational. For example: 2% is not irrational. 55.443% is not irrational. sqrt(5)% is irrational.
Is 1/5 irrational number?
No. Irrational numbers can not be expressed as a ratio between two integers.
What is an irrational number between 5 and 7?
4*sqrt(2) Rational multiples of irrational numbers are irrational. sqrt(2) is about 1.414, and 5/4 = 1.25 < 1.414... < 1.75 = 7/4 so 4*sqrt(2) is between 5 and 7, and is irrational.

What are 3 examples of a real number that is not an irrational number?
5, 6.5, 1/2
What irrational number is the golden ratio?
1 + sqrt(5)/2 is.
Are set of irrational number closed under addition?
No. 2 + sqrt(5) and 2 - sqrt(2) are both irrational but their sum, 4 is rational.
