What is the inverse of the log function?
This is a general formula that you should memorize. The inverse of is . You can use this formula to change an equation from a log function to an exponential function.
Example Question #3 : Logarithms And Exponents
Solve for :
Round to the nearest hundredth.
Cannot be computed
To solve this, you need to set up a logarithm. Our exponent is . The logarithm's base is . The value is the operand of the logarithm. Therefore, we can write an equation:
Now, you cannot do this on your calculator. Therefore, using the rule for converting logarithms, you need to change:
to...
You can put this into your calculator and get:
, or rounded,
