Question

If x = ( √7 - √6 ) / (√7 + √6 ) and y =( √7 + √6 ) / (√7 - √6 ) , then the value of x + y is


​

Answer 1

Answer:

the value of x+y is 26.

Step-by-step explanation:

x={(√7–√6)/(√7+√6)}×{(√7–√6)/(√7–√6)}

=(√7–√6)²/{(√7)²-(√6)²}

=(7+6–2√42)/(7–6)= (13–2√42)

y={(√7+√6)/(√7–√6)}×{(√7+√6)/(√7+√6)}

=(√7+√6)²/{(√7)²-(√6)²}

=(7+6+2√42)/(7–6)= (13+2√42)

Now,

x+y= 13-2√42+13+2√42

= 13+13

= 26..
