well that is ur problem

OpenStudy (anonymous):

?

OpenStudy (johnweldon1993):

try
\[3\sqrt{6}\]

OpenStudy (anonymous):

it said simplify not evaluate

OpenStudy (anonymous):

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

OpenStudy (johnweldon1993):

3 * sqrt(6)

OpenStudy (anonymous):

that is 7.32

OpenStudy (anonymous):

3 * sqrt(6)
just as is

OpenStudy (anonymous):

so is it 7.32 or 7.34

OpenStudy (johnweldon1993):

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

the answer is 7.32

OpenStudy (johnweldon1993):

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

OpenStudy (anonymous):

are you asking me or her

OpenStudy (johnweldon1993):

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