find log(0.5679×0.0789/0.0073×0.123) by logarithm table
Answers
Answer:
0.5679×0.0789/0.0073×0.123
The complete question is :
find by logarithm table
The value of the logarithmic expression is 1.6982 as calculated using logarithm tables.
The expression is
We will use the logarithmic properties to simplify the above expression.
We know the logarithmic multiplication rule as :
The logarithmic division rule is :
Now we will use these rules for the complex expression:
Now we will find the individual values of the logarithms using the logarithm tables:
log 0.5679
Here the mantissa = -1 (0.5679<0)
Characteristic (from the log table) = 0.7643
Similarly, we will find each logarithmic value.
log 0.0789
mantissa = -2
Characteristic = 0.8971
log 0.0073
mantissa = -3
Characteristic = 0.8633
log 0.123
mantissa = -1
Characteristic = 0.0899
Now we will use these values :
Therefore the value of the logarithmic expression is 1.6982.
