Question

explain whether 3 x 12 x 101 + 4 is a prime of a composite number

Answer 1

given number is
3×12 ×101+4
12 can be written as 3×2×2
and 101 can be 3×37
therefore it can be
3×3×2×2×3×37+2×2
by the fundamental theorem of arthimetic
every composite number can be expressed as product of primes
hence it is a composite number
