㏒₆
(1)/(36)
so 6² = 36
therefore, 6⁻² =
(1)/(36)

so your answer will be -2
the power is the answer

Answer: The log simplifies to -2

-------------------------------------------
-------------------------------------------

Step-by-step explanation:

We will use the log rule that log(x^y) = y*log(x). Call this log rule 1. This log rule basically allows us to pull the exponent down.

Another log rule that we will use is
\log_x\left(x\right) = 1 where x is any positive real number but x = 1 is NOT allowed. Call this log rule 2.

Because 36 = 6^2, this means that 1/36 = 6^(-2)

-------------

So,


\log_6\left((1)/(36)\right)=\log_6\left((1)/(6^2)\right)


\log_6\left((1)/(36)\right)=\log_6\left(6^(-2)\right)


\log_6\left((1)/(36)\right)=-2*\log_6\left(6\right) Use log rule 1 (see above)


\log_6\left((1)/(36)\right)=-2*1 Use log rule 2 (see above)


\log_6\left((1)/(36)\right)=-2

This means that the given expression simplifies to -2

You can use a calculator to type in "log(1/36)/log(6)" without quotes and you should get -2 as the answer
