\[\LARGE \log(2.23)+\log( 6.022)+{23} + 3\log(3.608)-24\]
example^^

nah :/ its a random no. :P
I was trying this..
\[\LARGE \frac{28.88}{2.39 \times 10^{-23}}\]
I got..
log(28.88) as 1.4606
log(2.39) as 0.3784
and log(10^-23) as -23
so..
1.4606-0.3784+23
24.0822?

see the table
you may use either log table or antilog table for that.
anyways, approximately,10^0.0822 is close to 10^0.1 i.e. it'll be around 1.2

you look for the mantissa in the antilogs table the same way as for the logs...
but only the mantissa.. not the characteristic.
electrokid
Best Response

1
then you put the number down and put a decimal the characteristic +1 number of digits from the left

0.3430 till here

what are we supposed to do with the decimal?
and another thing..
is antilog 3.532 same thing as
\[\large 10^{3.532}\] in this particular case
electrokid
Best Response

1
no we are not done..
we had to accomodate the characteristic.
once you get the 0.3430,
from the original number, the characteristic is "3"
so, we move the decimal point 4 digits to the right
so, antilog of 3.5352 = 3430.0

if you had 1.5352
its antilog would have been
34.30
