There's an equation I have to use in my cosmology exam and I cannot make it work! I decided to practice using the example in my textbook but no matter how I input it, I cannot get the answer they have. Any ideas?

Example is:

r = 1 x 10 to the 41 over 4 pi x 9 x 10 to the minus 10 W m to the minus 2. The whole of that is inside the square root symbol.

The answer they have is 9 x 10 to the 48 m to the 2 under the square root symbol.

HELP!!!
 
LOL!

Eventually managed to figure it out, just required some very inventive ways of entering info into a calculator!!!
 

well done :) I get stumped with even the simplest maths :blush:
 
I'm very dim. I don't even know what cosmology is and what you will do with it when you get it! Sorry absolutely no help at all. But good luck to you with it. :wave:
 
Well Done Sophie - I'd have tried to help you but hey now you don't need it!
 
Come back in a couple weeks when you need help with covariant tensors. :thumbsup2

Are you sure this is cosmology, not cosmetology? :rotfl:
 
lol, I don't know what I'm going to do with it either!! This course is coming to an end now, just have this exam (quantum physics pt 2, cosmology and astronomy) then I have to write a paper about Life on Mars!!

Just about to start my 2 summer short courses, The Planets and Mammal Biology.
 
Does this officially make you a rocket scientist? that's got to be the coolest thing to put on a CV :cool1:
 
Hahaha, I doubt it! I think to be able to put in on your CV it helps to actually understand it as well. Most of my work so far has been looking it up in the index and hoping!
