समुच्चय $8x \equiv 6(\bmod 14),\,x \in Z$, का हल है

A

$[8] \cup [6]$

B

$[8] \cup[14]$

C

$[6] \cup [13]$

D

$[8] \cup [6] \cup [13]$

Solution

$8x – 6 = 14P(P \in Z)$ ==> $x = \frac{1}{8}[14P + 6]\,,\,x \in Z$

==> $x =$ $\frac{1}{4}(7P + 3)$$  ==> x = 6, 13, 20, 27, 34, 41,48,…….$

$\therefore $ हल समुच्चय $= \{6, 20, 34, 48,…..\} = \{13, 27, 41, ……\} = [6] [13]$ जहाँ $[6], [13] $ क्रमश: $ 6 $ और $13$  की तुल्यता कक्षा है।
