got a question. FAN AND MEDAL

OpenStudy (anonymous):

What's your question

OpenStudy (needhelpinalgebra):

simplify

OpenStudy (needhelpinalgebra):

possible answers 5 1/4 5 1/12 5 7/12 5 4/3

OpenStudy (needhelpinalgebra):

@pink33

OpenStudy (needhelpinalgebra):

@AndrewIsHere

OpenStudy (andrewishere):

It is 3/4

OpenStudy (anonymous):

the answer is 3/4

OpenStudy (needhelpinalgebra):

I don't have that as an option.

OpenStudy (andrewishere):

The \[\sqrt{5}\] divides out

OpenStudy (needhelpinalgebra):

so, D?

OpenStudy (andrewishere):

thats its reciprocal

OpenStudy (andrewishere):

3/4 = .75 4/3 = 1.33

OpenStudy (needhelpinalgebra):

then.... wtf? this is just confusing.

OpenStudy (andrewishere):

yeah the question just says to simplify?

OpenStudy (needhelpinalgebra):

yeah. and those are the options.

OpenStudy (andrewishere):

wait what is the 5 in front?

OpenStudy (needhelpinalgebra):

no clue. this is confusing.

OpenStudy (andrewishere):

yeah i dont understand the answer choices

OpenStudy (needhelpinalgebra):

Find an equivalent function to f(x) = 5(3)^3^x. (5 points) f(x) = 125^x(27)^x f(x) = 15^2^x f(x) = 5(27)^x f(x) = 135^x

OpenStudy (andrewishere):

Oh wait

OpenStudy (andrewishere):

omg

OpenStudy (andrewishere):

I just figured it out

OpenStudy (needhelpinalgebra):

what???

OpenStudy (andrewishere):

I thopught it was saying 3*squareroot of 5 divided by 4*squarerrot of 5

OpenStudy (andrewishere):

its the cuberoot of 5 divided by the fourth root of 5

OpenStudy (needhelpinalgebra):

hmmm........ uhhh which answer would that be?

OpenStudy (andrewishere):

its 5 1/12

OpenStudy (andrewishere):

Geez

OpenStudy (needhelpinalgebra):

lmao. thanks. what about that other one?

OpenStudy (andrewishere):

Ok so 5*3 is what

OpenStudy (andrewishere):

?

OpenStudy (needhelpinalgebra):

5 times 3 is 15.

OpenStudy (andrewishere):

Good now cube it. 15*15*15 + ?

OpenStudy (andrewishere):

The plus is supposed to be an =

OpenStudy (needhelpinalgebra):

3375?

OpenStudy (andrewishere):

Good so the equation is really 3375^x

OpenStudy (needhelpinalgebra):

hmm. ok

OpenStudy (andrewishere):

Go down your choices and substitute 1 for x, which would make out current formula = 3375. Now we have to find one that gives us 3375 as well. In the first one it would be (125^1) * (27^1), which is really 125*27, which equals 3375

OpenStudy (andrewishere):

BINGO

OpenStudy (andrewishere):

To check, if you divided 3375 by 125, you would get 27 If you divided 3375 by 27, you would get 125

OpenStudy (andrewishere):

But I do have to go but I hope that helped

OpenStudy (needhelpinalgebra):
