Q. 1 let a+b+c+d = x
then,
x + 1/x = 2
= x² + 1 = 2x
= x² - 2x +1 = 0
= (x - 1 )² = 0
= x = 1
putting value in
x^6 + 1/x^6
1 + 1 = 2
Q. 2
let the number be x and y
then, according to question
x² + y² = 497
and
x + y = 23
So,
( x + y )² = 23²
x² + y² + 2xy = 529
497 + 2xy = 529
2xy = 529 - 497
xy = 32 / 2
= 16
Q. 3
First solve the numerator
( 12.425 )² - ( 5.575 )²
= ( 12.425 + 5.575 ) ( 12.425 - 5.575 )
( a² - b² ) = ( a + b ) ( a - b)
= 18 × 6.85
Now denominator
7.655 + 1.345
= 9
So the answer is
( 18 × 6.85 ) / 9
= 2 × 6.85
= 13.7

then,
x + 1/x = 2
= x² + 1 = 2x
= x² - 2x +1 = 0
= (x - 1 )² = 0
= x = 1
putting value in
x^6 + 1/x^6
1 + 1 = 2
Q. 2
let the number be x and y
then, according to question
x² + y² = 497
and
x + y = 23
So,
( x + y )² = 23²
x² + y² + 2xy = 529
497 + 2xy = 529
2xy = 529 - 497
xy = 32 / 2
= 16
Q. 3
First solve the numerator
( 12.425 )² - ( 5.575 )²
