Question

simplify (5+route5)+(5-route5)

Answer 1

Step-by-step explanation:

$(5 + \sqrt{5} )(5 - \sqrt{5} ) \\ = 15 - 5 \\ = 10$

Answer 2

Step-by-step explanation:

if question is (5 + √5)(5 - √5)

$(5 + \sqrt{5} )(5 - \sqrt{5} ) \\ = {5}^{2} - {( \sqrt{5}) }^{2} \\ = 25 - 5 \\ = 20$

if the question is (5+√5) + (5 - √5)

$5 + \sqrt{5} + 5 - \sqrt{5} \\ = 5 + 5 \\ = 10$

Hope you get your answer
