they have to be in the same units for starters

10^3 Kg = 10^3 * 1000 grams

Now divide the weight of the giraffe by the weight of the ant  (all in grams)

I did one of these for you before - You try and do it and if you can't tell/shoe me what you have tried 

enter it on the home page calc as  sqrt(89)=

If you want to do it on the forum calc then there is a post in the  sticky topics telling you how.

OR

do you want to know how to do it by hand?

Thank you Jacquess.   Enyoy your holidays and have a great 2015   :)    

Thank you Rosala.

Happy New Year DavidQD

Happy New Year NotTheBestMathMaster   :)

It is great to see you back on the forum David. 

I thought you must have been incorporated as one with the cosmos :)))))

What you need to recognise here os that ln2 is just a constant so the derivative is just ln2× e^x

You take the mass of the whale and divide it by the mass of the ant.

I did one of these for you yesterday.  I want you to copy the technique and try it for youself.

Put as much as you can do here then I can check your answer or help you with the bits that you don't understand.  

Happy New Years Eve  

I wish you all a wonderful 2015

You know for a long time I have thought that Santas red and white outfit was the direct result of coca cola advertising in the early 1950s but according to this artical that is not true.
