Hi.

 

Logarithmic functions are the inverse of exponents, which means...

 

an exponent, say a^b, is b number of a's multiplied together.

 

On the other hand.

 

Loga (b) is asking a to the what power is b?

 

So we are solving for x where a^x = b.

 

Thus, say, log. base 10(this is the "a") of 1000, is 10^x = 1000, x = 3.

 

Log2 (8) = 3.

 

If you don't understand anything feel free to ask!

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.

 

For example, 10^3 = 1,000; therefore, log10 1,000 = 3.
