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

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

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

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
