To find: Which value of n makes the value of the expression 4n+3 a composite number is it.
Solution : We have given 4n + 3.
Composite number : A composite number is a positive integer which is not prime (i.e., which has factors other than 1 and itself).
For, n = 3
4 (3) + 3
12 + 3
15 .
We can see 15 is not a prime number . it has factor 3 , 5, 15 .
So, For n = 3 the expression 4n+ 3 is composite number.
Therefore, C )For n = 3 the expression 4n+ 3 is composite number.
