PLEASE SOLVE QUESTION 13 AND 14 <br>DONT STEAL THE POINTS ​
Varvara68 [4.7K]

Answer:

See below for solution.

Step-by-step explanation:

Q13) \frac{\sqrt{11} - \sqrt{5} }{\sqrt{11}+\sqrt{5}  } = x - y\sqrt{55}

<u>LHS :-</u>

= \frac{\sqrt{11} - \sqrt{5} (\sqrt{11}-\sqrt{5})  }{\sqrt{11}+\sqrt{5} (\sqrt{11}-\sqrt{5})  }

= \frac{11-2\sqrt{55}+5 }{11 - 5}

= \frac{16-2\sqrt{55} }{6}

= \frac{2(8-\sqrt{55}) }{2(3)}

= \frac{8-\sqrt{55} }{3}

=> x = 8/3 and y = 1/3

=> <u>Option B</u>

<u></u>

<u></u>Q14) \frac{4}{216^{-2/3} } + \frac{1}{256^{-3/4} } + \frac{2}{243^{-1/5} }

= 4 x (∛216)² + (\sqrt[4]256})³ + 2 x (\sqrt[5]{243})

= 4 x 36 + 64 + 2 x 3

= 144 + 64 +6

= 144 + 70

= <u>214</u>
