ANYONE GOOD AT ALGEBRA? please help :)

s=(r((6+i)^n-6))/i

I need to solve for r

s=r(6+i)^n-6) then that all over "i" as a fraction

please help me understand how to do this. ty so much

endoftheside

si=r(6+i)^n -6
si+6 = r(6+i)^n
(si+6)/((6+i)^n) = r

Since there is only one r, you need to separate all the other stuff from around the r, paying attention to order of operations to keep the right things together.

First multiply both sides by i, cancelling out the i on the right side. Then add 6 to both sides, cancelling out the 6 on the right side. Then multiply by 1/(6+i)^n on both sides, cancelling it out on the right side and leaving only r.

My brain just cramped up reading that. :ohwell:

si=r(6+i)^n -6
si+6 = r(6+i)^n
(si+6)/((6+i)^n) = r

Looks good to me!

Wow,
I thought I was getting old! I actually understood that :-)

The first answer was absloluely correct. That was an easy one. Have anything harder?

Awwww just what I was going to say......probs

Also, if someone failed to mention remember that i = sqr -1

Depends on the teacher, but some may want you to give the answer in rational form.

Do your own homework

False, aliens DO wear hats. Irrational... and more math words. Lolz.

I think it may be more complicated on that, depending on how the problem is supposed to read. OP originally posted

s=(r((6+i)^n-6))/i

followed by

s=r(6+i)^n-6) then that all over "i" as a fraction

In the second version, there is one too many ")". In the first, if accurate, the entire ((6+i)^n-6) would be multiplied by "r", preventing you from simply adding 6 to both sides of the equation.

If I'm incorrect, please let me know. I'm blonde and it's still early.

ETA: If it IS supposed to be written the way you interpretted it, I agree with your math completely.

faster_than_flash

First answer is correct.

Grab a ti-89 calculator - It can solve and check this for you.

Also look at wolframalpha.com.

I'm good at math, but I prefer to give lessons in biology as payment beforehand.

I rather do it the easy way if you understand the problem I see... just multiply by i then exchange r and s... you don't need to go through a whole bunch of other processes if R is on the outside and you can just multiply by the reciprocals.

The first answer is beautifully precise and explained quite well. My compliments to the prof.

That's what got me stuck because I kept trying to multiply the R, and started to FOIL the 6+i till I realized the exponent was N!

I did the same thing at first. If the way she wrote it is correct, it should be r = (si)/((6+i)^n -6)

Apparently I'm not. I tried to solve the problem to see if I'm even qualified to give you instructions.............NOPE. Good luck.

i would like to thank everyone who tried and help me very nice of you. i knew i would get some negative comments but that's okay i understand that's not what this site is made for but almost everyone on here is so nice that's why i decided to ask.


thanks again everyone
