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
7 + 5 + 4 ÷ 2 + 7 = 21
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

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.

Every irrational number, when multiplied by 0.4 will produce an irrational number.
