<span>How
the value of 8 in 880 related
=> 880 = 8 hundreds 8 tens
=> This given number is a whole numbers, thus the value of 8 in the hundreds
place is ten times larger than the 8 In the tens place. How?
Try multiplying 8 tens by 10
=> 8 tens = 80
=> 80 x 10
=> 800
When 80 is multiplied by ten the answer is 800 and when 800 is divided by 10
the answer is 80.
That concludes that there’s 10 times difference between the two 8s in the given
number.</span><span>

Answer:
34
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
Step-by-step explanation:
(2x-y+3)(2x-y-3)=
4x²-2xy-6x-2xy+y²+3y+6x-3y-9=
4x²-4xy+y²-9=
(2x-y)²-9
