Im stuck on this differentiation equation, Ill post what I have done, im close to the answer in the back, but not there.

The question is Given that for f(x) = (x^5/2)/5 + 64/x, find the values of x and y when f'(x) = 0

well the f'(x) means dy/dx which of the above is

1/5 x^5/2 + 64x^-1

dy/dx = 5/10 x^3/2 -64x^-2 = f'(x)

Now if the f'(x) = 0 then 5/10 x^3/2 - 64x^-2 = 0

Now im not factorising so I solved for x and did

1/2 x ^3/2 = 64/x^2

(1/2)(x^3/2)(x^2) = 64
(x^3/2)(x^2) = 64/(1/2)
x^7/2 = 128
x^7 = 128^2
x^7 = 16384
x = 16384^1/7
x = 4

Now much to my horror the answer in the back is 4.57

No idea where I have gone wrong....any pointers would be great

I'm an 18yr old male, college student, residing in Los Angeles California and on July 3rd am going to be in China for about 4 weeks.

This is my 1st time travelling outside the United States and have never obtained a passport. Therefore am completely clueless on how to obtain one; especially in a shorter amount of time since the trip is a mere six (6) weeks away.

Luckly I live about 2 blocks from a post office and I know they do passports there but can someone fill me in on what I need to do to get one? Especially in this short amount of time?

What do i need, when do i need it and how soon?

Is there anyway I can speed things up by doing them online?

Website links and valuable information is greatly appreciated. Thanks!!!!!!!!!!!!!!!

Well. Christians tend to believe it's wrong, but god made us to be how we are right? He is all mighty and powerful, so he didn't make anyone gay. I suppose homosexuality is a result of too much sugar, or is some infection going around, BEWARE don't touch the gays, it's contageous!!! No i don't think so, it's strange, homosecuality is not a Decision made by a person, it is their nature. If god made them he made them to be gay. Are you saying that people Choose to be gay? No. Many children have grew up having homosexual feelings, not a choice they made.

I have a girl who lives 2 houses down who is drop dead gorgeous. The other night we hung out and partied and fooled around a bit. After that I didn't see her for a while and if I did, she would be with her friends or some other guys. I absolutely cannot stop replaying everything in my mind and critiquing it and determining what I should have said and shouldn't have. Should I just go over to her house and talk to her? How do I get her attention again without sounding desperate and what do I say? I am a college guy who doesn't do that great at partying, I can't dance, and I don't have a ton of friends b/c they are all out of state, she on the other hand is a great partyier who knows what shes doing and seems to have many friends. This makes me nervous that I will seem like a "loser" to her. Advice?

i came up with a question. woulden't you agree the gay relationships are just a tad bit better because your dating someone like you. i mean, you have the same anatomy you both basically like the same thing (ex: girls like the whole romance thing, candles, dinner, getting in the right mood, guys just like to get right to sex) so dont you think its a bit better? and they're both happy with each other.

You know definetely this woman is his friend because she is almost 20 years older than your husband . The thing is, of course I don't mind if she call my husband but once this lady calling, she will talk between 1-2 hours. She is a single parent so I know maybe she needs somebody to talk to. My husband is a very good listener, so that's why. She doesn't really call that much, like once in a month. but still, I'm not really happy when she call my husband. Could I tell her not to talk to my husband on the phone for a long time? Because my husband also has things to do not only to listen to her complaints/story.

For people who can't sing (like me) if you could sing, who would you want your voice to sound like?
I don't mean you'd actually be them - i mean you'd still be you but with their voice

I would want the voice of Angela Gannon from The Magic Numbers or Eva Cassidy.
