Question

hello,
simplify using identity
(√5-√2)(√5+√2)​

Answer 1

Using identity a² - b² = (a+ b)( a-b)

(√5-√2)(√5+√2)

= √5² -√2²

= 5 - 2

= 3

.

Hope it helps uh!

Keep calm and study hard

Thanks for asking

Answer 2

Answer:

The answer is - Hence simplified using identity

Ans. 3

Step-by-step explanation:

To simplify using identity

$(\sqrt{5} - \sqrt{2})(\sqrt{5} + \sqrt{2})$

Simplify using the identity $(\sqrt{a} - \sqrt{b})(\sqrt{a} + \sqrt{b})$ = a - b

So,

$(\sqrt{5} - \sqrt{2})(\sqrt{5} + \sqrt{2})$ = 5 - 2[using identity $(\sqrt{a} - \sqrt{b})(\sqrt{a} + \sqrt{b})$ = a - b]

                                 = 3(Answer of the question)
