यदि $A \times B =\{(a, x),(a, y),(b, x),(b, y)\}$ तो $A$ तथा $B$ ज्ञात कीजिए।
If is given that $A \times B=\{(a, x),(a, y),(b, x),(b, y)\}$
We know that the Cartesian product of two non-empty sets $P$ and $Q$ is defined as
$P \times Q=\{(p, q): p \in P, q \in Q\}$
$\therefore $ $A$ is the set of all first elements and $B$ is the set of all second elements.
Thus, $A=\{a, b\}$ and $B=\{x, y\}$
यदि $ A, B$ तथा $C $ तीन समुच्चय हैं, तब $A × (B \cap C) $ बराबर है
यदि $ A = \{2, 3, 5\}, B = \{2, 5, 6\}, $ तब $(A -B) × (A \cap B) $ है
मान लीजिए कि $A =\{1,2,3\}, B =\{3,4\}$ और $C =\{4,5,6\} .$ निम्नलिखित ज्ञात कीजिए
$(A \times B) \cap(A \times C)$
मान लीजिए कि $A =\{1,2,3\}, B =\{3,4\}$ और $C =\{4,5,6\} .$ निम्नलिखित ज्ञात कीजिए
$A \times(B \cup C)$
जब $n(A) = 4$, $n(B) = 3$, $n(A \times B \times C) = 24$, है तो $n(C) = $
