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

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

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

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