How do I condense each expression?

Ksivusya [100]

Answer:

$\log_5{\dfrac{x^5}{\sqrt[4]{8-x}}}$

Step-by-step explanation:

Make use of the rules of logarithms:

log(a/b) = log(a) - log(b)

log(a^b) = b·log(a)

$5\log_5{x}-\dfrac{1}{4}\log_5{(8-x)}=\log_5{x^5}-\log_5{\sqrt[4]{8-x}}=\log_5{\dfrac{x^5}{\sqrt[4]{8-x}}}$

Which of the following explains why f(x) = log2x

Radda [10]

Answer:

There is no power of 2 that is equal to 0.

Its inverse does not have any x-intercepts.

Step-by-step explanation:

Given the function

$\:\:f\left(x\right)=\log \:_2\left(x\right)$

This function can be written as:

$y=\log _2\left(x\right)$

As the rule tells s that

$\:y=log_ax\Rightarrow \:a^y=x$

$x=2^y\:\:$

As we know that the value of x=0 at y-intercept.

$0=2^y\:\:$

For any value of $y$ , this statement is false as there is no power of 2 that is equal to 0.

Also

Lets interchange x and y in the equation $x=2^y\:\:$ to find the inverse of the function.

$y=2^x\:\:$

So, it doesn't have any x-intercepts as for any value of x, the value of $y$ can not be zero for this function.

Therefore, Its inverse does not have any x-intercepts.

Find the functions y-intercept algebraically

grigory [225]

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y. If the equation is written in the slope-intercept form, plug in the slope and the x and y coordinates for a point on the line to solve y. Hope this helped! :)
