See http://mathforum.org/library/drmath/view/52619.html for a proof of the irrationality of sqrt(3). The proof that sqrt(5) is irrational is identical (substituting 5 for 3 in the proof).

∙ 14y agosqrt 45 = sqrt 5 x sqrt 9 = 3 sqrt 5. Sqrt 5 is irrational so 3 root 5 is also irrational.
I would answer no because 3√2 ____ 5√2 Would simplify to 3 divided by 5 and that is not irrational.
Yes, irrational. Let p = root 2 and q = root 3. Then (q - p)2 = 5 - 2root6, which is irrational because it is the sum of an integer (5) and an irrational (2root6), and so q - p (which is root3 - root2) is irrational.
They are +5 and -5, which are both rational.
The square root of 75 is an irrational number and it is 5 times the square root of 3
Yes, the sqrt of (3+5) is irrational, because: sqrt(3+5) = sqrt of 8, which is irrational
IRRATIONAL sqrt(15) = sqrt(3 x 5) =sqrt(3) X sqrt(5) Since the 'square roots' of prime numbers , '3' & '5' in this case, are irrational , then the square root od '15' is irrational .
sqrt 45 = sqrt 5 x sqrt 9 = 3 sqrt 5. Sqrt 5 is irrational so 3 root 5 is also irrational.
This is an easy question : root 2, root 3, root 5. Any square root of an integer which is not integral itself is irrational.
no. an example of an irrational number would be like the square root of 3
I would answer no because 3√2 ____ 5√2 Would simplify to 3 divided by 5 and that is not irrational.
Square root of 2, square root of 3, square root of 5, pi, e
Yes, irrational. Let p = root 2 and q = root 3. Then (q - p)2 = 5 - 2root6, which is irrational because it is the sum of an integer (5) and an irrational (2root6), and so q - p (which is root3 - root2) is irrational.
under root 2, under root 3, under root 5,under root 6.
They are +5 and -5, which are both rational.
The square root of 75 is an irrational number and it is 5 times the square root of 3
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.
