Question

Evaluate by using suitable identity

Answer 1

Answer:

200

Step-by-step explanation:

a² - b² = (a + b)(a - b)

$\frac{113^2 - 87^2}{113 - 87}$ = $\frac{(113 - 87)(113 + 87)}{113-87}$ = 113 + 87 = 200

Answer 2

$\huge{\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}!$

$a² - b² = (a + b)(a - b)</p><p></p><p>\frac{113^2 - 87^2}{113 - 87}113−871132−872 = \frac{(113 - 87)(113 + 87)}{113-87}113−87(113−87)(113+87) = 113 + 87 = 200</p><p></p><p>$
