Question

If x is a positive rational number which is not a perfect square then value of -5√x is ?

Answer 1

Step-by-step explanation:

Yes, unless X is a perfect square, sqrt(X) is irrational. The proof where X= 2 is an example of the general proof: Suppose sqrt(X) is rational, then there exists integers p and q such that (p/q)^2 = 2, we can cancel any common factors out of p and q so these are the simplest integers which satisfy the equation
