Answer:
your answer is as follows:
Step-by-step explanation:
(i) 5 x 11 x 13 + 13
5 x 11 x 13 + 13 = 13( 5 x 11 x 1 + 1)
= 13( 56)
= 13 x 56
By Fundamental theorem of Arithmetic, it's a composite number.
(ii) 6 x 5 x 4 x 3 x 2 x 1 + 5
6 x 5 x 4 x 3 x 2 x 1 +5 = 5( 6 x 1 x 4 x 3 x 2 x 1 +1)
=5(145)
=5 x 145
By Fundamental theorem of Arithmetic, it's a composite number.
hope you get it!!
