Question

simplify ((√5-√2) (√5+√2) ​

Answer 1

Answer:

your answer is 3 hope it helps........

Step-by-step explanation:

(√5-√2)(√5+√2)= (√5)^2 - (√2)^2

[ as (a+b)(a-b)= a^2-b^2]

=> 5-2=3

Answer 2

Answer:

So the answer is 3

Step-by-step explanation:

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

We know that ( a - b ) ( a + b ) = a^2 - b ^2.

$- > {( \sqrt{5} )}^{2} - ( { \sqrt{2} )}^{2}$

$- > 5 - 2$

$- > 3$

i hope it helps u dear friend ^_^♡♡
