For any positive number b not equal to 1 and any number or variable n, evaluate the following expression.
kirza4 [7]

Answer:

 log_{b} b^{n} = n.

Step-by-step explanation:

Given :  log_{b} b^{n} , b is any positive number not equal to 1 and n is any number.

To find : Evaluate the expression  log_{b} b^{n}.

Formula used : log_{b} x^{y}. = y ∙ log_{b}(x) and

log_{b}(b) = 1.Solution : We have  [tex]log_{b} b^{n}.

By logarithm rule :  log_{b} x^{y}. = y ∙ log_{b}(x).

Then  log_{b} b^{n} = n∙ log_{b}(b).

By logarithm rule :  log_{b}(b) = 1.Now, n∙ [tex]log_{b}(b) = n.

Therefore,  log_{b} b^{n} = n.

What is the slope of the line that passes through the points (-1,1) and (1,-15)​
Luda [366]

Answer:

  • \boxed{\text{The slope is -8.}}

Step-by-step explanation:

To find the slope of the line, you have to use a slope formula.

<u>Slope formula:</u>

\Longrightarrow:\sf{\dfrac{y_2-y_1}{x_2-x_1} }

⇒ y2=(-15)

⇒ y1=1

⇒ x2=1

⇒ x1=(-1)

<u>Rewrite the whole problem down.</u>

\Longrightarrow: \sf{\dfrac{-15-1}{1-\left(-1\right)}=\dfrac{-16}{2}=\boxed{\sf{-8}}

  • <u>So, the slope is -8, which is our answer.</u>

I hope this helps you! Let me know if my answer is wrong or not.
