The square root of 0.49 is 0.7 which is a rational number because it can be expressed as a fraction in the form of 7/10
The argument why the square root of 2 is irrational can be found in most high school algebra books. You can also find this proof, and several other proofs, that the square root of 2 is irrational, in the Wikipedia article "Square root of 2".The same argument can be applied to the square root of any natural number that is not a perfect square.
10+0.01 = 10.01 and it is a rational number
The principal (square) root of 10 is an irrational real number which equals approximately 3.16227766.
2.5 is the ratio of 25 to 10 ... entirely rational.
It is irrational.
It is neither but if you mean the square root of 100 then it is 10 which is a rational number
5
As √10 is irrational, 18 + √10 is irrational.
It is 10 which is a rational number.
The result would be an irrational number
It is irrational because it can't be expressed as a fraction.
The square root of 9 is a rational number. This is because the square root of 9 is equal to 3, which can be expressed as a fraction, 3/1. In general, a rational number is any number that can be expressed as a ratio of two integers, which is the case for the square root of 9.
The square of 100 is 10000, which is rational.The square root of 100 is 10, which is also rational.
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. In general, the square root of a positive integer is either a whole number, or an irrational number.
The square root of 0.49 is 0.7 which is a rational number because it can be expressed as a fraction in the form of 7/10
