If x=3+root8 and y =3- root 8 find 1/x^2+1/y^2

KonstantinChe [14]

Answer:

Step-by-step explanation:

x=3+√8

y =3-√8

now,

1/x^2+1/y^2

=1/(3+√8)² + 1/(3-√8)²

= [(3-√8)²+(3+√8)²] / (3+√8)²(3-√8)² [L.C.M = (3+√8)²(3-√8)² ]

=[(3-√8+3+√8)²-2(3-√8)(3+√8) ] / [(3+√8)(3-√8)]²

=[6²-2.(3²-√8² )] / (3²-√8²)² [ a²+ b²=(a+b)²-2ab]

=[36-2(9-8) ]/ (9-8)²

=[36-2.1] / 1²

=34

C) Bhurashi can do 1/3 part of a work in 6 days.

Simora [160]

Answer:

Step-by-step explanation:

$\frac{1}{3}$ part of work can be done in 6 days.

Days taken to complete the whole work:

= 6 * 3

= 18 days

ii. Whole work will be done in 18 days.

So, 1 day work = $\frac{1}{18}$

iii. Work done in 9 days :

$\frac{1}{18} \times 9$

$= \frac{1}{2}$

So, remaining work :

$1 - \frac{1}{2}$

$= \frac{1 \times 2 - 1}{2}$

$= \frac{2 - 1}{2}$

$= \frac{1}{2}$ part of work

Hope this helps...
