What is the value of the rational expression below when x is equal to 4? x-12/x-8
Firlakuza [10]

Answer:

When x=4 we get the value of the given expression is

\frac{x-12}{x-8}=2

Step-by-step explanation:

Given rational expression is \frac{x-12}{x-8}

To find the value of the given rational expression \frac{x-12}{x-8}

when x is equal to 4 :

That is the value of the given rational expression \frac{x-12}{x-8}

when x=4 :

\frac{x-12}{x-8}

Put x=4 in the above rational expression we get

\frac{4-12}{4-8}

=\frac{-8}{-4}

=\frac{8}{4}

=2

Therefore  when x=4 we get the value of the given expression is

\frac{x-12}{x-8}=2

Write the expression as a monomial in its standard form.<br><br> 9/16p^7 ⋅ (-4/3p^4)
Aleksandr-060686 [28]

Answer:

-3/4 p^11

Step-by-step explanation:

9/16p^7 ⋅ (-4/3p^4)

Multiply the numbers together

9/16 * -4/3 = -3/4

Now multiply the variables

p^7 * p^4

We know that a^b* a^c = a^(b+c)

p^(7+4) = p^11

Putting these back together

-3/4 p^11
