Is square root of 100 irrational or rational?
Square root of 100 is a rational number. Because sqaure rooot 100 = 10. And, 10 can be written in the form rational number. Any number that can be written in the form of p/q where p and q are integers and q in not zero is called a rational number.
For this case we have the following number:
\(\sqrt{100}\)
By power properties we can rewrite the number.
We have then:
\(\sqrt{100} = \sqrt{10*10}\)
\(\sqrt{100} = \sqrt{10^2}\)
\(\sqrt{100} = 10\)
We observe that the result can be written as the quotient between two whole numbers.
For example:
\(\frac{200}{20} = 10\)
This means that the number is rational.
Answer:
square root of 100 is rational.
