If Log 20 = 1.301 what is the value of Logsub100 20?
Charra [1.4K]

Answer:

log_{100}20 = 0.6505

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:

10^{1.301} = 20  (This is the log in exponential form)

Since we don't know what  log_{100}20  is equal to, we will say  log_{100}20 = x

So to solve for log_{100}20 = x, you do the same thing. (convert to exponential form)

100^{x} =20

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

Since 20 = 20,

we can say 100^{x} = 10^{1.301}

Another way of saying 100, is 10^{2} (make the bases the same)

Now we get 10^{2x} = 10^{1.301}      

(we get 2x because an exponent to the power of an exponent (2^{x}) 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
