Answer 3

As @Christina42872 has said

Answer 4

thnx but i dont have a twitter

Answer 5

thats what i put and it was wrong :(

Answer 6

well that is ur problem

Answer 7

?

Answer 8

try

\[3\sqrt{6}\]

Answer 9

it said simplify not evaluate

Answer 10

when it evaluate then you put 7.34....
when it is simplify you the the 3 sqrt(6)

Answer 11

exactly @timo86m

Answer 12

so its 7.34 oh ok :) yay

Answer 13

no!

Answer 14

yes it is see i was right

Answer 15

no that would be evaluating..you're simplifying

Answer 16

3 * sqrt(6)

Answer 17

that is 7.32

Answer 18

3 * sqrt(6)
just as is

Answer 19

so is it 7.32 or 7.34

Answer 20

just think of it like this

what is

\[\sqrt{54}\]

it can be written as
\[\sqrt{9}\sqrt{6}\]

right? because the squareroot of 9 times the square root of 6 is the square root of 54 right?

so what is the square root of 9? 3

so your answer is 3 * square root 6

Answer 21

the answer is 7.32

Answer 22

let me ask you

if I asked you to simplify x * x ...what would you say that is? x² correct?
now what if I asked you to EVALUATE x * x ? what would you say? you don't know it.

the difference between evaluating and simplifying

Answer 23

are you asking me or her

Answer 24

either...I'm trying to point out...that the question asked to simplify...not solve...the answer would be 3 * square root 6
