Answer 2

You can rule out 2 answers in the first problem, just by using your calculator. Which ones are those?

Answer 3

A and B

Answer 4

Yup! The next thing you need to do is simplify the equation. So first, you need to simplify \[\sqrt{18}\]. What numbers go into 18?

Answer 5

ahhh D :D

Answer 6

Yup! D is right for the first one. Now the next one, what I always do for these kind of problems is I substitute 1 for x and solve all of the answers and see which one is equal to the original equation. It's probably not the best way, but it works.

Answer 7

\[\sqrt{18}=\sqrt{9\times2}=3\sqrt{2}\]

Answer 8

shouldn't that be B?

Answer 9

@Sparklestaraa
Actually, I don't know! I tried plugging in 1, but none of them match the answers?!? Umm. Help! @sammixboo @jagr2713 @jagatuba @Hero @dan815 @Abhisar

Answer 10

what number are we on?

Answer 11

second one

Answer 12

\[x \sqrt{a}+y \sqrt{a}=(x+y)\sqrt{a}\]

Answer 13

what is that :O

Answer 14

this is first which already have solved

Answer 15

what about C?
\[\left( 1.04 \right)^{4x}=\left\{ \left( 1.04 \right)^4 \right\}^x=\left( ? \right)^x\]

Answer 16

ahhh yes C :D
