Styrofoam!

Because it's white and pretty and in a billion years it will be the only evidence of our exsistence!

Doesn't have any bones either.

correct, you win the prize behind door number one.

If I break Ohm's law will I go to jail?

if you do, you'll probably have a stop at the hospital to ease the transition.

Who's got?

5^y=4^(y+3)


Show your work.

haha... good question.

I will take "who gives a crap" for $200 Alex...

haha... good question.

5^y = 4^(y+3)
y log5 = (y+3) log4
.6990y=(y+3).6021
.6990y=.6021y+1.8062
0.969y= 1.8062
y=18.64

work with logarithms often?

i'm lucky i remembered what i did. it's been 15yrs since i've used it.

jake... where were you when i could have used those links? :shakehead:

the answer is 288. Try rewriting the equation as 48/2(9+3)
