Verified answer

(√3)+(√5)= ?

its A because you can't add this equation and get an answer unless you plug it into a calculator, but that will just give you a decimal answer. which is 3.968

A) (√3)+(√5) =/= √8 ( does not equal symbol =/=)

B) (√3)+(√5) = √8

sq rt 8 = 2.828

so its not b

C) (√3)+(√5) = √15

sq rt of 15 is 3.872

so its not c

D) (√3)+(√5) = (3/2) + (5/2)

this is just 8/2 when you simply and you get and answer of 4 which isn't equal to the left side of the equal sign either.

A) √3 + √5 =/= √8. True.

If i square both sides, I end up with a 2√15 = 0, which is not true.

B) √3 + √5 = √8. False.

Just disproved that.

C) √3 + √5 = √15. False.

It ends up being 2√15 = 7.

D) √3 + √5 = 4. False.

It ends up being 2√15 = 8.

continually follow exponents first, then cross with multiplication so (-five)^two = 25 then 25*(-three) = -seventy five standard order is exponents, multiplication and department, addition and subtraction

pretty sure B.

but check your book!
