Answer:

The answer is (d) ⇒ $pq^{2}r\sqrt[3]{pr^{2}}$

Step-by-step explanation:

* To simplify the cube roots:

If its number then the number must be written in the form x³

then we divide the power by 3 to cancel the radical

If its variable we divide its power by 3 to cancel the radical

∵ $\sqrt[3]{p^{4}q^{6}r^{5}}=p^{\frac{4}{3}}q^{\frac{6}{3}}r^{\frac{5}{3}}}$

∴ $p^{\frac{4}{3}}q^{2}}r^{\frac{5}{3}}=p^{1\frac{1}{3}}q^{2}r^{1\frac{2}{3}}$

∵ $p^{\frac{1}{3}}=\sqrt[3]{p}$

∵ $r^{\frac{2}{3}}=\sqrt[3]{r^{2}}$

∴ $p(p)^{\frac{1}{3}}q^{2}r(r)^{\frac{2}{3}}=p(\sqrt[3]{p})q^{2}r(\sqrt[3]{r^{2}})$

∴ $prq^{2}\sqrt[3]{pr^{2}}}$

∴ The answer is (d)

36-(b^2+c^2-2bc)=36-(b-c)^2=6^2-(b-c)^2= (6+b-c)[6-(b-c)]=(6+b-c)(6-b+c)

Can someone explain to me how to do this exercise?

kolbaska11 [484]

Hi
You should put into them.I mean
1-This is 2 part.First, you should put f(-1) then you should put what you found.
Solve is:f(-1)=3(-1)-2(-1)^2 so -3-2=-5 then put in other one:if f(-5):-15-50=-65
Is it correct?

What is the slope of the line that passes through the points (-8, -1)(−8,−1) and (-6, -2) ?(−6,−2)? Write your answer in simples

ziro4ka [17]

The slope of line passing through the given points is: -1/2

Step-by-step explanation:

Given points are:

(x1,y1) = (-8,-1)

(x2,y2) = (-6,-2)

Slope is defined as the steepness of a line.

It is denoted by m.

The formula for slope is:

$m = \frac{y_2-y_1}{x_2-x_1}$

Putting the values

$m = \frac{-2-(-1)}{-6-(-8)}\\= \frac{-2+1}{-6+8}\\=\frac{-1}{2}$

The slope of line passing through the given points is: -1/2
