C-02-Q095mediumsingle_mcq

For an ordered pair, the pair $(x, y)$ equals $(a, b)$ if and only if—

a $x = b$ and $y = a$
b $x + y = a + b$
c $x = a$ and $y = b$
d $xy = ab$

ব্যাখ্যা

Two ordered pairs are equal only when their corresponding components match exactly—the first with the first and the second with the second. So $(x, y) = (a, b)$ requires $x = a$ and $y = b$ .
