What is the prime number and composit numbers |
|
Answer» Thank you Prime NumbersA\xa0prime number\xa0is the one which has exactly two factors, which means, it can be divided by only “1” and itself. But “1” is not a prime number.Example of Prime Number3 is a prime number because 3 can be divided by only two number’s i.e. 1 and 3 itself.3/1 = 33/3 = 1In the same way, 2, 5, 7, 11, 13, 17 are prime numbers.Composite NumbersA\xa0composite number\xa0has more than two factors, which means apart from getting divided by number 1 and itself, it can also be divided by at least one integer or number. We don’t consider ‘1’ as a composite number.Example of Composite Number12 is a composite number because it can be divided by 1,2,3,4,6 and 12. So, the number ‘12’ has 6 factors.12/1 = 1212/2 =612/3 =412/4 =312/6 =212/12 =1 Composit is jo 2 s jiyada 3 4 5 6 other number s divisible h that is composit number |

The sum of two numbers is 9 and the sum of their resiprocal is 1/2 . Find the numbers |
|
Answer» The sum of two numbers is 9 and the sum of their reciprocal is 1/2.Let the numbers be x and y respectively.Sum of numbers is 9.⇒ x + y = 9.... (i)⇒ y = 9 - x .... (ii)Sum of reciprocals is 1/2.⇒\xa0.... (iii)Now, on solving (iii),Putting the value of (i) and (ii) here, we get -Hence, the required numbers are 6 and 3. By not going to solve whole we can say that 3+6=9 and by its reciprocal we are getting 1/2 |

Prove that 3+√5 is irratonal |
|
Answer» Let us assume 3+root 5 to be rational.It means that it can be written in the form of p/q where p and q are coprime and q is not equal to zeroL.H.S*p/q=3+root5*p/q-3=root5L.H.S i.e.p/q-3 is rational but R.H.S i.e. root 5 is irrational So our assumption is wrong Therefore 3+root5 is irrational. Hence proved Let us assume that\xa03+5\u200b\xa0is a rational number.Now,3+5\u200b=ba\u200b\xa0[Here a and b are co-prime numbers]5\u200b=[(ba\u200b)−3]5\u200b=[(ba−3b\u200b)]Here,\xa0[(ba−3b\u200b)]\xa0is a rational number.But we know that\xa05\u200b\xa0is an irrational number.So,\xa0[(ba−3b\u200b)]\xa0is also a irrational number.So, our assumption is wrong.3+5\u200b\xa0is an irrational number.Hence, proved. |
