1.67 is the ratio of 167 to 100. That's rational.

6.45 is the ratio of 645 to 100 ... nice and rational.

Yes, 102 isn't a square number (1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144) so the square root of 102 will keept going forever and is irrational.

If you are expected to calculate it without a calculator then the first step is to write the fraction as a ratio - a top heavy one if necessary. You will find that the numerator and denominator of the rational fraction are both perfect square numbers. Then the square root of the ratio is the ratio of the square roots.For example, to find the square root of 11.11... recurring.You know that, since it is a recurring decimal, the number is rational.In ratio form, this number is 100/9 and sosqrt(11.11...) = sqrt(100/9) = sqrt(100)/sqrt(9) = 10/3 = 3.33... recurring.

It is a rational number because it can be expressed as a fraction in the form of 1269/100

No. However, the square root of any positive integer that is NOT a perfect square, IS irrational.

It is neither but if you mean the square root of 100 then it is 10 which is a rational number

The square of 100 is 10000, which is rational.The square root of 100 is 10, which is also rational.

It is 10 which is a rational number.

It is irrational, because it is not a perfect square. For example, if you have a number that is perfect like the square root of 100, it would be 10, which is a rational number. An irrational number like 16.4 which would be a not so accurate result like 6.447583839, those are irrational numbers. Hope this helps!

No. The square root of most numbers is irrational - only if the number of which you take the root happen to be perfect squares, do you get a rational root. In this case, to take the square root of 3/4, 3 is not a perfect square, so the root is not rational. Or you can take .75 to be 75/100; once again, 75 is not a perfect square, so the root is irrational.

It is neither, it is an imaginary number.

no. the square root of 100 is 10.

Yes because the square root of a 100 is 10 which is a rational number

No, its a rational number.No. 100 is rational- in fact an integer and a perfect square.

The square root of a 100 is 10 which is a rational number

The square root of 100 is 10, and it is a rational number.
