No because 2+7 = 9 which is a rational number
Yes the result would be an irrational number.
4*sqrt(2) Rational multiples of irrational numbers are irrational. sqrt(2) is about 1.414, and 5/4 = 1.25 < 1.414... < 1.75 = 7/4 so 4*sqrt(2) is between 5 and 7, and is irrational.
No. A rational plus an irrational is always an irrational.
irrational
The square root of 28 is irrational. This is because 28 is not a perfect square, and its prime factorization (2² × 7) includes a prime factor that cannot be paired evenly. Consequently, the square root of 28 can be expressed as 2√7, where √7 is irrational, making the entire expression 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
Yes the result would be an irrational number.
4*sqrt(2) Rational multiples of irrational numbers are irrational. sqrt(2) is about 1.414, and 5/4 = 1.25 < 1.414... < 1.75 = 7/4 so 4*sqrt(2) is between 5 and 7, and is irrational.
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.
No. A rational plus an irrational is always an irrational.

The square root of 28 is irrational. This is because 28 is not a perfect square, and its prime factorization (2² × 7) includes a prime factor that cannot be paired evenly. Consequently, the square root of 28 can be expressed as 2√7, where √7 is irrational, making the entire expression irrational.
Every irrational number, when multiplied by 0.4 will produce an irrational number.
