It is an irrational number.

Yes. In fact, a rational plus or minus an irrational will always be irrational.

Irrational.

Yes because a rational number can be expressed as a fraction whereas irrational numbers can't be expressed as fractions.

Any number with a defined end-point, such as -0.4744, is rational.

17 is a prime number with no factors other than itself and 1 therefore minus square root of 17 is an irrational number.

Minus pi. Or minus pi plus any rational number. Here is how you can figure this out (call your unknown number "x", and let "r" stand for any rational number):x + pi = r To solve for "x", simply subtract pi from both sides. That gives you: x = r - pi

If you mean 36 minus 25 then the square root of 11 is an irrational number

Let your sum be a + b = c, where "a" is irrational, "b" is rational, and "c" may be either (that's what we want to find out). In this case, c - b = a. If we assume that c is rational, you would have: a rational number minus a rational number is an irrational number, which can't be true (both addition and subtraction are closed in the set of rational numbers). Therefore, we have a contradiction with the assumption that "c" (the sum in the original equation) is rational.

No because all integers positive or minus are rational numbers

A negative irrational number can be thought of as an irrational number multiplied by -1, or an irrational number with a minus sign in front of it.

You can also have any numbers like (a + c) and (b - c), where "c" is the irrational part, and "a" and "b" are rational.

If the positive square root (for example, square root of 2) is irrational, then the corresponding negative square root (for example, minus square root of 2) is also irrational.

This can easily be proved by contradiction. Without loss of generality, I will take specific numbers as an example. The proof can easily be extended to any rational + irrational number. Assumption: 1 plus the square root of 2 is rational. (It is a well-known fact that the square root of 2 is irrational. No need to prove it here; you can use any other irrational number will do.) This rational sum can be written as p / q, where "p" and "q" are whole numbers (this is basically the definition of a "rational number"). Then, the square root of 2, which is equal to the sum minus 1, is: p / q - 1 = p / q - q / q = (p - q) / q Since the difference of two whole numbers is a whole number, this makes the square root of 2 rational, which doesn't make sense.

No - expressed as a fraction in its simplest form, -0.45 is equal to -9/20 or minus nine twentieths.

yes, rational numbers are numbers that can be formed as a fraction hence -5/1 even with a minus sign on it irrational numbers are surd numbers, numbers that cant be expressed as a fraction

a minus and a plus equal a minus number yeh dude

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, nor is it a real number. The square root of minus 54 is equal to the square root of plus 45, times i.

A negative rational (also real) number.

A negative number minus a positive number will always be a negative number.

It is equal to the number of neutrons in the given atom.

Minus two.Some rational numbers are positive, some are negative. -9 is a negative rational number.
