## MiaKitty 3 years ago Need Help!!! Please help! I need it badly! 10.04] Simplify the expression. the square root of the quantity 27 x to the fifth power, plus x times the square root of 3, plus nine times the square root of the quantity 3x If the simplified expression is written in standard form, what is the leading coefficient?

1. MiaKitty

Simplify this also, thx!

2. jlongSwag27
3. MiaKitty

What? That isn't very helpful!

4. MiaKitty

OMG ! Does nobody know this?

5. iNeedTheHelp

√(27x^4) + x√(3) + 9√(3x) Complete the squares to get.. 3x²√(3) + x√(3) + 9√(3x) = (3x² + x)√(3) + 9√(3x)

6. MiaKitty

What is the leading coefficient?

7. MiaKitty

Is it 3?

8. MiaKitty

or is it 2?

9. MiaKitty

9?

10. iNeedTheHelp

I gave you all the help I can give for now because you're not suppose to give answers just plug in all the numbers that I gave you and you'll figure it out (: Good luck~

11. MiaKitty

OK, um, can you tell me if I'm right, at least?

12. MiaKitty

Or tell me what a coefficient is?

13. MiaKitty

Because I don't know. :)

14. iNeedTheHelp

Its a number that is used to multiply by a variable

15. iNeedTheHelp

I suggest Khan Academy for a research tool it helped me alot (: www.khanacademy.org <---- Really good resource.

16. MiaKitty

ch, I will check it out! That;s all I need to know. >:)

17. iNeedTheHelp

Ok Goodluck >:)

18. MiaKitty

Thx, it was kind iof u to help out! :D

19. MiaKitty

I still need help with coefficents, but Im fine. :)

20. iNeedTheHelp

Ohh I answered your question about coefficients up there :)

21. MiaKitty

Yup! Thx, I just need the coefiicent for the problem, I am checking.

22. MiaKitty

If I know any better, I am going to say 3. :)
