I'm hung up on these... its for a math summer review packet and I can't figure it out.

the directions say: "Rewrite using properties of logs and exponents"

ln(4xsinx)


and the other:

e^(3+x) (the carrot (^) indicates an exponent)

If you can help w/ step by step at least to get me started... that would be great.

Thanks

On talk sport this morning they gave a mathematical riddle
Three men enter a motel only to be told that there's only one room left, by the young girl at reception, they are shattered so they agree to share, they ask how much it will be and are told £30, great they say that's £10 each. When the manager gets back the girl tells him she's let the room, only for him to tell her, she'd made a mistake and the room only costs £25. At this the girl takes £5 in £1 coins up to the room, the girl apologises and tells the men they can have the money back, because it's an odd amount, they say they'll have a £1 back each and the girl can have the remaining £2. this means that they have paid £9 each. So whats happened to the other £1?

i.e. 3x£9 =£27 remainer £3, but the girls only holding £2.

This is a serious question and I hope I can make myself clear.
When people state their ethnicity, I understand if they say "I'm 1/2 " this or I'm "1/4" this.

a)when does this get to be silly (meaning statistically or scientifically irrelevant) in your opinion, at 1/8th? 1/16 ?

b) Must it be an even number? What combinations are possible? Can someone say they are 1/3 or 1/5 or whatever or is this sort of meaningless because you have to go back too many generations?


Sorry if this doesn't make sense. I'm very smart but math sort of makes me freak out. thanks!
