Explain whether the number 3x5x13x46+23 is a prime number or a composite number.

3 x 5 x 13 x 46 + 23 is a composite number.

this is because,

3 x 5 x 13 x 46 + 23

= 23 ( 3 x 5 x 13 x 2 + 1)

= 23 ( 390 + 1 )

= 23 x 391 = 8993.

since 8993 is a product of 2 distinct  numbers, hence it is a composite number.
