What is 2^1/4 + 2^1/4 + 2^1/4 + 2^1/4 in the form of 2^p/q? I'm just a bit unsure of it, i think i know how to go about doing it, but i might be wrong...
2 to the first maybe, i know it is .5 +.5+.5+.5 Either way, do your own homework.
I don't know what p/q is but if I had to guess I'd say that the answer is 2.
Does it look like this on paper: [img]http://img214.imageshack.us/img214/5849/equation.png[/img]? If so, it probably is [img]http://img100.imageshack.us/img100/2783/equation2.png[/img], but I have no clue how to transfer it to a power of 2.
2^1/16 could be wrong though [editline]16th November 2010[/editline] I am pretty sure it's that. [editline]16th November 2010[/editline] no wait [editline]16th November 2010[/editline] I don't know.
2^(2+1/4)? or 2^9/4
Hey we're doing this in Pre Calc if I remember right. Pretty sure its 2^1/1, so 2.
2^4/4 or 2^1/1? [editline]16th November 2010[/editline] or 2 [editline]16th November 2010[/editline] No, I don't think that's right.
4*2^(1/4) = 2^2 * 2^(1/4) = 2^(2+(1/4)) = 2^(9/4)
Are you REALLY asking us to do YOUR homework?
[QUOTE=rawr >:3;26103803]Are you REALLY asking us to do YOUR homework?[/QUOTE] No, he is asking ONE problem he needs help with.
Sec... 2^9/4 same as 512^(1/4) which is the same as 2^(9/4)
