EVALUATE .LOG 243_LOG27
To evaluate .LOG 243_LOG27, we need to first understand the meaning of the notation '.LOG'. In mathematics, the notation '.LOG' usually represents the logarithm with base 10.
To calculate the logarithm of a number with base 10, we use the formula:
LOG (base 10) x = log10(x)
In this case, the expression .LOG 243 indicates that we are taking the logarithm of 243 with base 10.
Now, let's calculate the logarithm of 243 with base 10 using this formula:
LOG (base 10) 243 = log10(243)
To find the value of log10(243), we can use a scientific calculator or an online logarithm calculator to evaluate it.
After evaluating the expression log10(243), we find that it is equal to 2.385.
Therefore, the value of .LOG 243_LOG27 is 2.385.
If you meant
log 243 - log27 , then you have
log(243/27)
= log 9
