Answer:
C) 3
Step-by-step explanation:
This is just a differences of squares:
[tex](a+b)(a-b)=(a^2-b^2)\\\\(\sqrt{5}+\sqrt{2})(\sqrt{5}-\sqrt{2})=(\sqrt{5}^2-\sqrt{2}^2)=5-2=3[/tex]
Answer:
(c) 3
Step-by-step explanation:
[tex](\sqrt{5} +\sqrt{2} )(\sqrt{5} -\sqrt{2} )=(\sqrt{5} )^{2} -(\sqrt{2} )^{2} =5-2=3[/tex]
Hope this helps
