Fifty six radical two
Fifty six radical ten
Two hundred eighty radical four

Answer 1

first you would just multiply the square root parts together

Answer 2

=

Answer 3

sqrt(A) * sqrt(B) = sqrt(A*B)
sqrt(8) * sqrt(5) = ?

Answer 4

40?

Answer 5

Wait what?!?!?

Answer 6

good, sqrt(40)

now we just multiply the non-radical parts to get 7 * 4 = 28

Answer 7

now we go back to our sqrt(40) and see if we can factor out any perfect squares

Answer 8

40 = 4*10

sqrt(40) = sqrt(4)*sqrt(10)

sqrt(4) = ?

Answer 9

square root of 4 is 2

Answer 10

good, so sqrt(40) = sqrt(4)*sqrt(10) = 2*sqrt(10)

so let's put everything together

28* 2*sqrt(10) = 56sqrt(10) = C
