Question

prove that :7*13*4*3*2+12 is a composite number.​

Answer 1

Step-by-step explanation:

7×13×4×3×2=2184

2184+12=2196

2196 has more than two factors so it is a composite number

Answer 2

= 7 x 13 x 4 x 3 x 2 + 12

= 12 ( 7 x 13 x 4 x 3 x 2 + 1 )

= 12 ( 7 x 13 x 12 x 2 +1 )

= 12 ( 7 x 13 x 24 + 1 )

= 12 ( 91 x 24 + 1 )

= 12 x 2184 + 1

= 12 x 2185

we that that a no. which have 2 or more facotors called COMPOSITE NUMBER .

and it has two factor so it is an COMPOSITe no .
