Question

Explain why 5 x 7 x 13 + 5 is a composite number.

Answer 1

Solution:

x = 5 × 7 × 13 + 5

take 5 as common

x = 5(7×13+1)

x = 5(91 +1 )

x = 5 × 92

Since, x as two factors 5 and 92 it is composite number

Answer 2

Solution:

x = 5 × 7 × 13 + 5

take 5 as common

x = 5(7×13+1)

x = 5(91 +1 )
