Answer 1

$\star\:\:\:\bf\large\underline\blue{Question:-}$

• Using suitable identities evaluate.

$\star\:\:\:\bf\large\underline\blue{Solution:-}$

$23 \times 25$

$= (24 - 1)(24 + 1)$

$= {24}^{2} - {1}^{2}$

$= 576 - 1$

$= 575$

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• $23 \times 25 = 575$

$\star\:\:\:\bf\large\underline\blue{Identity\:Used:-}$

• $(x + y)(x - y) = {x}^{2} - {y}^{2}$

$23 \times 25</p><p>$

$\green{= (24 - 1)(24 + 1)}$

$= {24}^{2} - {1}^{2}$

= 576 - 1=576−1

= 575=575
