Question

simplify the expression:
sqrt(27x^5) + x sqrt(3) + 9 sqrt(3x)
If the simplified expression is written in standard form, what is the leading coefficient?

Answer 1

help me please

Answer 2

\[27x^5+x \sqrt{3}+9\sqrt{3x}\]is it yours?

Answer 3

yes

Answer 4

no,\[\sqrt{27x^5}\] it is the first term, right?

Answer 5

oh yea

Answer 6

so, what do you want? simplify or find coefficient? haaa let electrokid helps you

Answer 7

well it says to simplify but all i need is the leading coefficient

Answer 8

\[\sqrt{27x^5}+x\sqrt{3}+9\sqrt{3x}\\
=3\sqrt{3}x^{5/3}+x\sqrt{3}+9\sqrt{3}\sqrt{x}\]

Answer 9

to me, the first term = (27)^1/2 * x^5/2
the second one = sqr(3) *x
yeap. agree

Answer 10

okay, what's the leading coefficient?

Answer 11

LOL do it. electrokid

Answer 12

what is your "standard form"???

Answer 13

the thing you told me, what's the coefficient of that?

Answer 14

i believe, the leading term would be the term with the highest power of "x"

Answer 15

which would be? I can't tell... :/

Answer 16

what do you want? x is coefficient of number or vice versa?

Answer 17

if that is what it is,
then arrange the above expression in decresing order of powers of "x" from left to the right

Answer 18

which is the leading coefficient of the simplified answer.

Answer 19

umm ok

Answer 20

the powers of x are:
5/3 1 1/2

Answer 21

5/2

Answer 22

@Hoa all yours

Answer 23

5/3? isn't 1 bigger than 5/3? or would it be 3?

Answer 24

@electrokid don't understand

Answer 25

i think the leading coefficient of the standard form is 3.

Answer 26

it is \(3\sqrt{3}\)

Answer 27

my bad.. the powers of "x" are:
5/2 1 1/2

Answer 28

okay thnx

Answer 29

yer welcome.
