## primeavlqueen22 Group Title Referring to the figure, simplify the expression. http://www.ppstest2.com/images2/AL9005.jpg one year ago one year ago

1. Christina42872 Group Title

just find the square root of 54

2. Christina42872 Group Title

7.34846922835

As @Christina42872 has said

4. Christina42872 Group Title

thnx but i dont have a twitter

5. primeavlqueen22 Group Title

thats what i put and it was wrong :(

6. Christina42872 Group Title

well that is ur problem

7. primeavlqueen22 Group Title

?

8. johnweldon1993 Group Title

try $3\sqrt{6}$

9. timo86m Group Title

it said simplify not evaluate

10. timo86m Group Title

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

11. johnweldon1993 Group Title

exactly @timo86m

12. primeavlqueen22 Group Title

so its 7.34 oh ok :) yay

13. timo86m Group Title

no!

14. Christina42872 Group Title

yes it is see i was right

15. johnweldon1993 Group Title

no that would be evaluating..you're simplifying

16. timo86m Group Title

3 * sqrt(6)

17. Christina42872 Group Title

that is 7.32

18. timo86m Group Title

3 * sqrt(6) just as is

19. primeavlqueen22 Group Title

so is it 7.32 or 7.34

20. johnweldon1993 Group Title

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

23. primeavlqueen22 Group Title

are you asking me or her

24. johnweldon1993 Group Title

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