(6 + root27)/(4 - root3) can be written in the form (r + sroot3)/13

Bogdan [553]

Answer:

r = 33 , s = 18

Step-by-step explanation:

Rationalise the denominator by multiplying both numerator and denominator by the conjugate of the denominator.

The conjugate of 4 - $\sqrt{3}$ is 4 + $\sqrt{3}$ , then

$\frac{(6+\sqrt{27})(4+\sqrt{3}) }{(4-\sqrt{3})(4+\sqrt{3}) }$ ← expand numerator/denominator using FOIL

= $\frac{24+6\sqrt{3}+4\sqrt{27}+\sqrt{81} }{16+4\sqrt{3}-4\sqrt{3}-3 }$

= $\frac{24+6\sqrt{3}+4(3\sqrt{3}+9 }{16-3}$

= $\frac{33+6\sqrt{3}+12\sqrt{3} }{13}$

= $\frac{33+18\sqrt{3} }{13}$

with r = 33 and s = 18

The general form of a circle is given as x^2 + y^2 + 4x - 12y + 4 = 0.

stepan [7]

If you can rewrite the formula as (x-a)² + (y-b)² = r², the center is at (a,b) and the radius is r.

If you work out this equation, and map it to the original, you will find that the +4x term hints that a = 2 (double product) and -12y hints that b=-6, and r=6.

So, the formula can be written as (x+2)² + (y-6)² = 6² and the center is at (-2,6) and the radius is 6.
