Question 108817: Express Log functions as exponentil functions:
a. Log m = 3 my answer:3
b. log 5 =y
c. ln b =2
For B and C I'm extremely unsure of how to do them, I do not even know where to start.
Thank you for your help.

Express Log functions as exponentil functions:
a. Log m = 3 my answer:3
b. log 5 =y
c. ln b =2
----------------
When you see logx = y you are saying "the exponent is y"
Keep in mind: log means "exponent" or "power"
-----------------
a. log m = 3
means "the exponent is 3"
m = 10^3 is the corresponding exponential equation.
==============
b. log 5 = y
means "the exponent is y"
5 = 10^y is the corresponding exponential equation.
-------------
c. ln b = 2
means "the exponent is 2"
b = e^2
=============
Cheers,

The log function, for base 10, gives you a number in the form of
.
In other words, for y=100, the log(y)=2, since .
Logarithms help because large numbers can be handled as small numbers.
Instead of using one million (1,000,000), I use log(1,000,000)=log(10^6)=6.
So what number is it when log(y)=3, then
a.)
b.)log (5)=y, what number do I need so that .
You can use a calculator, log tables, etc. to find the value.
It's greater than 0, since and less than 1 since .
y=0.699.
c.)Natural log is similar to log except the base is different (e vs. 10).
The natural log function, for base e, gives you a number in the form of
.
"e" is a special number in mathematics, equal to approximately 2.71828.
Similar to log function above, if ln(b)=2, then and
b= 7.388
