anyone can help me??? how -0.18 * log 0.18 - 0.2 * log 0.2 can be 0.722?

Answer 1

Try applying the BODMAS rule
(-0.18*log 0.18) - (0.2*log0.2)

=(-0.18 * -.7447) - (0.2 * -.6989)

=(0.134046) - (-0.13978)

= 0.2738.

I dont know why you feel the answer has to be 0.722...are you sure the data you've given is correct?
