how do you simplify the expression 3 root 7 over -1- root 27? please explain with details. does multiplying by conjugates work i
kap26 [50]

as you already know we'll be using the conjugate of -1-√(27), which is just -1 + √(27), so we can rationalize the denominator.


\bf \cfrac{3\sqrt{7}}{-1-\sqrt{27}}\cdot \cfrac{-1+\sqrt{27}}{-1+\sqrt{27}}\implies \cfrac{3\sqrt{7}(-1+\sqrt{27})}{\stackrel{\textit{difference of squares}}{(-1)^2-(\sqrt{27})^2}}\implies \cfrac{-3\sqrt{7}+3\sqrt{189}}{1-27} \\\\\\ \begin{cases} 189=3\cdot 3\cdot 3\cdot 7\\ \qquad 3^2\cdot 21 \end{cases}\implies \cfrac{-3\sqrt{7}+3\sqrt{3^2\cdot 21}}{-26} \\\\\\ \cfrac{-3\sqrt{7}+9\sqrt{21}}{-26}\implies \cfrac{3\sqrt{7}-9\sqrt{21}}{26}

A merchant wishes to blend 200 pounds of coffee worth $3.20 a pound from two mixtures: one at $3.00 a pound and the other at $3.
Fofino [41]
X pounds of $3
y pounds of $3.25

x+y = 200

300x + 325y = 320*200
300x + 325y = 64000

x+y =200
300x +325y =64000

Solve by eliminating

Multiply top one w/-300

-300y =60000
325y=64000
25y = 4000

y= 160 then

x + 160= 200

x = 40


So the mixture has;

40 pounds of $3 coffee
160 pounds of $3.25 coffee
