Question

if a and b are two composite prime number a2 -b2 is composite

Answer 1

Answer:

Step-by-step explanation:

1.we know a composite number has a divisor other than one.

2.A composite prime number has only two divisors i.e itself and one

3.now here a and b are two composite prime numbers and now if the difference of two squares is even , and even number has many divisors.

4.so the final conclusion is if and a,b are two composite prime numbers then a2-b2 is a composite number

Example : let a=7 ,b=5 a2=49 and b2=25

a2-b2=24 , is a composite number
