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

MissTica

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

Consider the attached function - The values are?

kow [346]

To find the value f(-7), we just need to evaluate the function at $x=-7$ . In other words, we are going to replace $x$ with -7 in the function:
$f(x)=( \frac{1}{2} )^x$
$f(-7)=( \frac{1}{2})^{-7}$
$f(-7)=128$

Similarly, to find the value of f(5), we just need to evaluate the function at $x=5$ . In other words, we are going to replace $x$ with 5 in the function:
$f(x)=( \frac{1}{2} )^x$
$f(5)=( \frac{1}{2})^{5}$
$f(5)=0.031$

We can conclude that $f(-7)=128$ and $f(5)=0.031$
