Answer 2

Answer:

20 is your answer.

Step-by-step explanation:

To find :-

• (5+√5) (5-√5)

Rule:-

• (a + b) (a - b) = a^2 - b^2

Now solve the problem according to rule.

$\tt \to\red {(5 + \sqrt{5} )(5 - \sqrt{5} ) \blue = {5}^{2} - { \sqrt{5} }^{2} } \\ \tt \blue= \red{ 25 - 5} \\ \tt \blue = \red{20}$
