Question

Can someone please help me with this homework problem I am stuck on. Simplify the expression (k1/4)^-6/(k^9)^1/2

Answer 1

not following... the equation I am trying to write is here is not easy for me. Let me try again. A fraction. Variable (K next to 1/4) to the power of -6 (the numerator), now the denom. variable (K to the ^9th power) to the ^ 1/2 power.

Answer 2

Well , this is my problem... I am totally lost on these type of problems. I need serious help.

Answer 3

I have been trying to follow my in class notes, look on line and I can't seem to figure it out.

Answer 4

so multiply 2 x 1/2?

Answer 5

1

Answer 6

the K?

Answer 7

I'm not following you, you said to multiply them so I did, it's 1. What is left, I don't know.

Answer 8

(k^9)^1/2 = K^( 9/2)

Answer 9

I don't know what do you mean by: K "next to" 1/4

Answer 10

ok... so how do I figure out 1/4 to the power of -6

Answer 11

well in the equation that is given to me the numerator (top) reads (K 1/4)^-6

Answer 12

K 1/4 doesn't make any sense !

Answer 13

tell me about it! it's in my math lab homework ... double checking right now

Answer 14

yep that is what it says... a variable in front of 1/4 on the numerator to the ^-6

Answer 15

says to simplifly, assume that all variables are posittive

Answer 16

take a look

Answer 17

Here K ^1/4

Answer 18

so (k^1/4)^-6
Can you repeat the exponent rule I've showed you?

Answer 19

multiply the exponents so 1/4 * -6?

Answer 20

ans -1 1/2 ?

Answer 21

so k^-1 1/2 over k ^9/2 is my answer?

Answer 22

= -6/4 = -3/2
Always keep fraction form :)

Answer 23

= 1/ [ k^(9/2) * k^( 3/2) ]

Answer 24

Now, since both terms have the same base K : add the exponents together!

Answer 25

wait.. I had to refresh my page. so to get rid of the neg... what did you do?

Answer 26

Now pay attention to get rid of negative sign, by moving the whole term down to the denom.

Answer 27

I apologize. I did read what you wrote. to me it just looks like you are multiplying the two. = 1/ [ k^(9/2) * k^( 3/2) ] Correct?

Answer 28

6

Answer 29

so K^6

Answer 30

To be precisely 1/ K^6

Answer 31

why the 1 in front?

Answer 32

You need to learn the exponential rule!

Answer 33

yes, so you changed the sign when you flipped it. I just have a hard time with the whole invisiable numbers thing! Sorry if I irritated you. I do appreciate the help greatly. =)

Answer 34

= 1/ [ k^(9/2) * k^( 3/2) ]

Answer 35

No, just know the rules when to multiply/ divide or add / subtract the exponents :)

Answer 36

I've been in excellerated courses for Algebra I and II over the past almost 10 wks now. Havn't had math in over 20+ yrs... I've very rusty. It was never a subject a liked. I'm struggling. Passed the 1st class with a C. I'll be happy if I can do the same with this class. Thanks again.

Answer 37

well, I may be back shortly... I have more problems to do shortly. I am writing step by step "how to" notes.

Answer 38

However I wouldn't recommend any one to take accelerated Algebra II!

Answer 39

I know! but it's part of the Univ. of Phoenix program. I guess I could have gone to regular JC but it would cost me. I'm on a GI Bill. Every penny not spent helps ;-)

Answer 40

This class is 5 wks long. I have two weeks left.

Answer 41

I thought I was okay on Foil but then he got into Quadratics, and now Raticals and I'm lost.

Answer 42

So it's obviously you're wasting your money! You practically learn nothing in such a short period :/

Answer 43

The exponent concept actually belongs to pre algebra, the teacher probably will just skim over it!

Answer 44

Well for this class maybe. The other classes I've learned quite a bit. I think it boils down to what your interests are and where your strenghts are as well. You have to do the work, bottom line

Answer 45

I think the bigger problem is I hate math. I keep trying to stay positive. I go to tutoring on mid week, then I blank out on quiz time =(

Answer 46

yesterday I was in my office all damn day working on 20 lousy problems

Answer 47

I just now am going back to work. Got a p/t job starting in a week.

Answer 48

before that I was working full time 60 hrs a week and had to quit cuz it was too much with school

Answer 49

yes... too many steps!!!

Answer 50

well, I have 10 problems to work on today. Then my goal is to work on more study notes for tomorrows quiz in class. Then pray tonight that I don't bomb it! More Khan videos to watch ;-)
