Is 11 squared rational or irrational?
It's the ratio of 121 to 1, so it's rational. I think the square of any rational number is a rational number. In fact, I'm sure of it, because I know how I could prove it.
Are all rational numbers whole numbers prove your answer?
No, they are not. 1/2 is a ratio of two integers and so it is rational. But it is not a whole number.
How can you prove that 6.34 is a rational number?
(A): 6.34*100 = 634 so 6.34 = 634/100 a ratio of two integers and so a rational number. (B): 6.34 is a terminating decimal - with two non-zero digits after the decimal point. So again, it is a rational number.
Math help can anyone show you how to do this please Prove or disprove that if a and b are rational number then a to the power of b is rational?
2 and 1/2 are rational numbers, but 2^(1/2) is the square root of 2. It is well known that the square root of 2 is not rational.
How do you figure out if a number is rational or irrational?
If the number can be expressed in the form a/b where a and b are both integers and b ≠ 0, then it is proved rational. If you want to prove that it is irrational, then there are many complicated and different steps depending on the type of irrational number. (Yes there are different types)

Which number can be multiplied to a rational number to explain that the product of two rational numbers is rational?
It must be a generalised rational number. Otherwise, if you select a rational number to multiply, then you will only prove it for that number.
Does there exist an irrational number such that its square root is rational?
No, and I can prove it: -- The product of two rational numbers is always a rational number. -- If the two numbers happen to be the same number, then it's the square root of their product. -- Remember ... the product of two rational numbers is always a rational number. -- So the square of a rational number is always a rational number. -- So the square root of an irrational number can't be a rational number (because its square would be rational etc.).

What fractional form of 9.546 to prove that it is a rational number?
9.546 as an improper fraction in its simplest form is 4773/500 which proves that it is a rational number
How can you determine if a number is rational?
If the number can be expressed as a ratio of two integer (the second not zero) then the number is rational. However, it is not always a simple matter to prove that if you cannot find such a representation, then the number is not rational: it is possible that you have not looked hard enough!
Who is the first person to prove that lightning is a form of electricity?
Benjamin Franklin was the first person to prove that lightning is a form of electricity.

How you prove that -if r is rational and x is irrational then prove that r x and rx are rational?
You cannot, because the statements are false! (The second is rational only if r = 0).
How do you prove 1.6 is a rational number?
1.6 = 16/10.This is a ratio in which both the numerator (16) and denominator (10) are integers. The ratio, therefore, represents a rational number.
