Academci team of Physics Wallah prepared NCERT Solutions for Class 6 Maths Chapter 3 Playing with Numbers with all steps required.

Suppose your collection of primes includes all the possible primes. What is your guess about the size of this collection? Does it contain only a finite number of integers, or infinitely many? Infect, there are infinitely many primes. This concept is very well explained in NCERT text book for class 6 Maths chapter-3. So, if we combine all these primes in all possible ways, we will get an infinite collection of numbers, all the primes and all possible products of primes. The question is – can we produce all the composite numbers this way? What do you think? Do you think that there may be a composite number which is not the product of powers of primes? Before we answer this, let us factorise positive integers, that is, do the opposite of what we have done so far. Find errorless NCERT Solutions for class 6 Maths check out Physics Wallah.
