if bar is with 1 then it means -1 and if bar is with 3 then it means -3

Answer 2

so, it is 0.0899-(-1.8435)-(-3.8751)-3.1065= 0.0899+1.8435+ 3.8751-3.1065 right?

Answer 9

quick question, you said logs so are the questions

log(0.0899) - log(1.8435)..?

Answer 10

no i want to ask simple is [log(0.7214)+log(20.37)-log(60.8)]
its answer is -1.3833 i want to ask how?

Answer 11

well I used base 10 logs and got -0.616736

Answer 12

me too, XD

Answer 13

if you use a different base, you'll have a different answer.

as an example base e logs gives -1.42009

Answer 14

from base 10 .... Log(0.7214)=-1.8582 + log(20.37)=1.3089 - log(60.8)=1.7839 ?

Answer 15

now........ -1.8582+1.3089-1.7839=-1.3833 the answer is confirm

Answer 16

well try it this way, using log laws

\[\log_{10}(\frac{0.7214 \times 20.37}{60.8}) = \]

wow for log(0.7214) I got -0.141824
log(20.37) I got 1.30899

and log(60.8) i got 1.7839

so there seems to be some difference.... unless there is a typo in the question.

hope this helps
