Question 25

An irreducible factor of $24x^2{y}^2$ is
(a) $x^2$
(b) $y^2$
(c) $x$
(d) $24x$

Answer 1

(c) $x$
$\to$A factor is said to be irreducible if it cannot be factorised further.
We have, $24x^2{y}^2$ = 2 x 2 x 2 x 3 x $x$ x $x$ x $y$ x $y$
Hence, an irreducible factor of $24x^2{y}^2$ is $x$.
