Web9 – x2 is an irrational number. x2 is an irrational number. x is an irrational number. Assume that x is a rational number. So we arrive at a contradiction. Our assumption that √ – is a rational number is wrong. Therefore, √ – is an irrational number. 7. Write a pair of irrational numbers whose sum is irrational. Solution: 8. WebProve that 3+2√5 is irrational. Medium Solution Verified by Toppr Let us assume 3+2 5 + is rational. So we can write this number as 3+2 5= ba ---- (1) Here a and b are two co-prime number and b is not equal to zero. Simplify the equation (1) subtract 3 both sides, we get 2 5= ba−3 2 5= ba−3b Now divide by 2 we get 5= 2ba−3b

Easy Solution Verified by Toppr Let us assume 6+ 2 is rational. Then it can be expressed in the form qp, where p and q are co-prime Then, 6+ 2= qp 2= qp−6 2= qp−6q ----- ( p,q,−6 are integers) qp−6q is rational But, 2 is irrational. This contradiction is due to our incorrect assumption that 6+ 2 is rational nissan morrow ga hours
