Hi all,

I cant seem to get the correct answer to this equation (attached image):

The answer is -0.06 as shown in the question, but when I complete it in my calculator I get a different answer

Staring at this question for hours now.

(What I do: I first complete the the 2nd bracket and then multiply that by 108/365 which gives me 0.02739. I then hit the Ln button on my calculator and do 2510/2600 and add that answer to my 0.02739. Next I type 0.2306 SQUAREROOT(108/365) which gives me -0.01847)

Any pointers would be really apprecaited.

Thanks everyone.
