If Log 20 = 1.301 what is the value of Logsub100 20? I need the step by steps! I can’t find anything videos online to teach this to me

Step-by-step explanation:

log20 = 1.301 (when you see only "log" with no base, it is taken as a base 10)

This basically means:

 (This is the log in exponential form)

Since we don't know what    is equal to, we will say   = x

So to solve for = x, you do the same thing. (convert to exponential form)

Now you will notice that both of these equations are equal to 20.

Since 20 = 20,

we can say =

Another way of saying 100, is (make the bases the same)

Now we get      

(we get 2x because an exponent to the power of an exponent () is the same as 2 * x)

Because you have the same base, you can just ignore the 10s and focus on the exponents. So you get:

2x = 1.301

x = 0.6505

y=x+9
