Question

What is the product of the radical expression? ( sqrt 2+ sqrt 10) (sqrt 2 - sqrt 10)

Answer 1

\[(\sqrt{2}+ \sqrt{10}) (\sqrt{2}-\sqrt{10})\]

Answer 2

A. \[-8\sqrt{\sqrt{10}}\]

B. \[12\]

C. -8

D. \[8\sqrt{2}\]

Answer 3

\[(\sqrt{2}+\sqrt{10})(\sqrt{2}-\sqrt{10})=\sqrt{4}+\sqrt{20}-\sqrt{20}-\sqrt{100}\]

Answer 4

that should be easy to simplify

Answer 5

ugh i cant understand

Answer 6

can you show me the answer and explain why it is that answer so i can do the next problems easier?

Answer 7

first you are multiplying each number, doesn't really matter if you do the square root right now
after multiplying you can clearly see that 20 - 20 = 0 so that's gone

Answer 8

now you are left with square root of 4 which is 2 cause 2*2 = 4 and square root of 100 which is 10 cause 10*10 =100

so 2-10 = ....

Answer 9

8

Answer 10

-8

Answer 11

there you go

Answer 12

so its C?

Answer 13

yep
