Question

question 1) (√3+√2)×(√3-√2).

Answer 1

Answer:

Step-by-step explanation:

(a+b)(a-b)=a²-b².

Therefore,

(√3+√2)(√3-√2)=(√3)²-(√2)²

=3-2

=1.

The answer is 1.

Answer 2

$( \sqrt{3} + \sqrt{2} )( \sqrt{3} - \sqrt{2} ) \\let \: \sqrt{3} = x \: \\ \sqrt{2} = y \\ (x + y)(x - y) \\ x {}^{2} - y {}^{2} \\ ( \sqrt{3} ) {}^{2} - ( \sqrt{2} ) {}^{2} \\ 3 - 2 \\ 1 \\ follow \: me$
