Question

(√2+√3)(√2-√3)=
Answer this qn

Answer 1

Answer:

(-1)

Step-by-step explanation:

It is in the form the identity (a+b)(a-b)

(a+b)(a-b) = a²-b²

So here a = √2 and b= √3

Substitute the identity .

(√2+√3)(√2-√3)= (√2)² - (√3)²

square and square root get cancels

2 - 3

-1

Answer 2

Answer:

The answer is -1

.

$( \sqrt{2} + \sqrt{3} )( \sqrt{2} - \sqrt{3} ) \\ \\ {( \sqrt{2} )}^{2} - {( \sqrt{3} )}^{2} \\ \\ cancel \: square \: with \: square \: root \: then \: we \: have \\ \\ 2 - 3 = - 1 \\ \\ this \: is \: ur \: required \: answer \: :):):):):)$
