Can someone help answer and explain to me how to solve this? log (lowercase 6) 1/36

Answer: The log simplifies to -2

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

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(\frac{1}{36}\right)=\log_6\left(\frac{1}{6^2}\right)

\log_6\left(\frac{1}{36}\right)=\log_6\left(6^{-2}\right)

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

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

\log_6\left(\frac{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

How would the expression x^2-7 be rewritten using Difference of Squares? please someone help me.
kondor19780726 [428]
Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results.
