(b) Composite
(c) Can't say
(d) None of these
If you know any short trick…then plz tell me

Answer 1

The answer is composite because (the fundamental theorem of arithmetic gurantees that this factorization is unique. Thus , the given no. is composite).

Answer 2

Answer:

first of all here is 5*2 ie 10 means no. has zero as unit place and then add 5.. means no. would be surely divisible by 5 ..so it would not be prime that will be composite with the factor of 5

Step-by-step explanation:

5*2 =10

10+5= 5

unit place value will be 5 which is divisible by 5
