The square root of 28 is the same as the 2 x the square root of 7. 7 is prime, and so the square root of 7 is irrational. Thus the square root of 28 is irrational.

It is irrational.

The square root of any positive integer can only be a WHOLE NUMBER or IRRATIONAL, so the square root of 7 is irrational.On the other hand, the sum of a rational and an irrational number is always irrational.

7 plus the square root of 5 is an irrational number because the square root of 5 is a never ending decimal number that can't be expressed as a fraction.

It is irrational. 133 = 7*17 and so is not the square of any rational number. Therefore its square root cannot be rational.

The square root of 49 is 7, so it is rational.

Rational because it is 7.

Well, first let's define a "real number." A real number is any number that's not imaginary. It can be rational or irrational. The square root of 7 is 2.64575131... and it goes on forever. This means it cannot be written as a simple fraction. We can give an estimate of the square root of 7 in a fraction form, but this is not the exact result. So, the square root of 7 is a irrational number.Since a real number can be irrational or rational, yes, the square root of 7 is a real 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

The √49 is 7. It is a rational number.

No because 7 is a rational number

It is an irrational number because it can't be expressed as a proper fraction

No because the square root of 0.49 is 0.7 which is a rational number that can be expressed as a fraction in the form of 7/10

The negative square root of 49 is -7. -7 is whole, integer, and rational number. It's not a natural or irrational number.

No because 7 squared equals 49 which is a rational number but the square root of 7 is an irrational number

No. The square root of 49 is plus or minus 7, both of which are integers. And integers are rational numbers - whether they are positive or negative.

It is an irrational number because it can't be expressed as a fraction

-4

No. The square root of 49 is plus or minus 7, both of which are integers. And integers are rational numbers - whether they are positive or negative.

No. Square roots of whole numbers that don't result in whole numbers (e.g. the square root of 64 is 8), are considered to be "irrational numbers".

Well, for example, the square root of 4 is 2, which is a rational number. As long as the number which is being square rooted is not a square number itself (i.e. 1, 4, 9, 16 etc.), then it will be irrational. So..... the square roots of 49, 100, 196, for example, are all rational numbers (7, 10 and 14 respectively.) They do not have to be integers. The square of of any rational number automatically has a rational square root eg the square root of 77.41792 is 77.4179 . Rational means expressable as a ratio of integers: 77.4179 is 774179/10000 .
