No, irrational numbers cannot be written in the form of a/b. 75 can be written as 75/1
The square root of 75 is an irrational number
Yes.
It is a rational number because it can be expressed as a fraction in the form of 75/1
No. The square root of most numbers is irrational - only if the number of which you take the root happen to be perfect squares, do you get a rational root. In this case, to take the square root of 3/4, 3 is not a perfect square, so the root is not rational. Or you can take .75 to be 75/100; once again, 75 is not a perfect square, so the root is irrational.

The square root of 75 is an irrational number
Yes.
The square root of (any number that isn't a perfect square) is irrational.
Square root of 75 is about 8.660254038 so it is 9
75 times 75 = 5625 which is a rational number

The square root of 75 is an irrational number and it is 5 times the square root of 3
75 times 75 = 5625 which is a rational number
The most basic example you can have entails adding the positive and negative of the irrational to get zero: e + -e = 0 Another example you can give is to use compound angle formulae with trig: sin(15 deg)cos(75 deg) + sin(75 deg)cos(15 deg) = sin(90 deg) = 1
The square roots of -75 are [ +5i sqrt(3) ] and [ -5i sqrt(3) ]. Both of them are irrational and imaginary.
