look a1 = 5 n=1 a2=20 n=2, etc..

It would be B because in a geometric sequence, you have \[\large ar ^{n1}\] and in finding our r, we take \(\large\frac{ a _{2} }{ a _{1} }\) and that is 4

This way you can eliminate A because term 2 doesn't match up... And I think Jhanny's right

thanks you that was heard

Jhannybean Group TitleBest ResponseYou've already chosen the best response.2
So we have a1 = 5, our r = 4 and plug it into our formula \[\large ar ^{n1}\]

What is the simplified form of the expression?dw:1369539526178:dw

Alright, for this one you have a variable with two different powers dividing eachother, and in this case, we can simply do this. \[\large \frac{ 1 }{ q ^{\color{red}{(33/4)8} }}\]

hmm...something seems wrong here.

\[\frac{ 33 }{ 4 }8*(\frac{ \color{green}{4} }{ \color{green}{4} })= \frac{ 33 }{ 4 }\frac{ \color{darkorchid}{32} }{ \color{darkorchid}{4} }\]

good :) so 3332 works the same way, it is also 1.

I have another quesiton if you are up to it?

Of course :) Math is a lot about understanding a problem as a whole and finding a relation to a technique method in solving, it's all patterns.

Jhannybean Group TitleBest ResponseYou've already chosen the best response.2
\[\large (3x ^{\color{forestgreen}{7/2}})^{\color{blue}{6}}(x ^{\color{green}{2}})^{\color{blue}{6}}\] here, we will start 1 part at a time. lets start with \(\large (3x ^{7/2})^{6}\)

ok what do we do next
 one year ago

Jhannybean Group TitleBest ResponseYou've already chosen the best response.2
we're going to multiply 6 to the 3 AND the x^(7/2)
 one year ago

Jhannybean Group TitleBest ResponseYou've already chosen the best response.2
Are you able to do that?
 one year ago

Jhannybean Group TitleBest ResponseYou've already chosen the best response.2
Hm.. not exactly, we have \[\large(3^{\color{blue}{6}})(x ^{\color{blue}{(7/2)(6)}})\] which gives us \[\large(729x ^{21})\]

A. 729x33 B. 3x33 C. 729x29 D. 3x29

Now that we've taken care of the first part, we can move onto the second part, which is \[\large (x ^{2})^{6} = x ^{\color{red}{6*2}}= x ^{\color{blue}{12}}\]
 one year ago

Jhannybean Group TitleBest ResponseYou've already chosen the best response.2
Now we can combine both parts together so we get \[\large (729x {^\color{green}{21}}) *(x ^{\color{green}{12}}) = 729x ^{\color{red}{21+12}}\]
 one year ago

Jhannybean Group TitleBest ResponseYou've already chosen the best response.2
And adding 21 + 12 for the exponent, you'll get your answer. i've done the rest
