Prove that 1 by root 7 is irrational number |
|
Answer» We can prove 1by root 7 irrational by contradiction .Let us suppose that 1by root7 is rational it means we have some co-prime integers a and b (b is not equal to 0)such that 1by root 7=a/bRoot7=b/a .....1RHS of 1 is irrational but we know that root7 is irrational.It is not possible which means our supposition is wrong.Therefore,1by root7 cannot be rational..Hence it is irrational.. for which value of k will the following pair of linear equation has no solution 3 X + Y is equal to 12 ke minus y x x + K minus y + Y 2 |
