How we prove √5 as irrational |
| Answer» Let take √5 as a rational numberIf a and b are two co-prime number and b is not equal to 0.We can write √5 = a/bMultiply by b both side we getb√5 = aTo remove root, Squaring on both sides, we get5b2 = a2 ……………(1)Therefore, 5 divides a2 and according to a theorem of rational number, for any prime number p which is divided \'a2\' then it will divide \'a\' also.That means 5 will divide \'a\'. So we can writea = 5cand putting the value of a in equation (1) we get5b2 = (5c)25b2 = 25c2Divide by 25 we getb2/5 = c2again using the same theorem we get that b will divide by 5and we have already get that a is divided by 5but a and b are co-prime number. so it is contradicting.Hence √5 is an irrational number | |

If d is the HCF of 45 and 27 find integers x and y satisfying d=27x+45y |
|
Answer» HCF of 45 and 2745 = (27 x 1) + 1827 = (18 x 1) + 918 = (9 x 2) + 0 Therefore, HCF = 99 = 27 – (18 x 1) = 27 – [45 – (27 x 1)] x 1 [since 18 = 45 – (27 x 1)] = 27 – [45 x 1 – 27 x 1 x 1] = 27 – (45 x 1) + (27 x 1) = 27 + (27 x 1) – (45 x 1) = 27{1 + 1} – (45 x 1) = (27 x 2) – (45 x 1) HCF of 45 and 27 in the form of 27x + 45 is (27 x 2) + (45 x -1).Hence, the values of x and y are 2 and -1.
