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:
1) 29.74*60=1,784.4 miles per minute
1,784.4= 1,784 4/10=
1,784 2/5 miles per minute
2) 29.74-8.23= 21.51=21 51/100
3) ???
4) 21.76*60=1,305.6=1,305 6/10
1,305 3/5
