Meaning of rational indice

Answer» HEY MATE HERE IS YOUR ANSWER. ✌✌❤❤

RATIONAL indice is a law.

The law of rational indices states that the intercepts, OP, OQ, OR, of the natural FACES of a crystal form with the unit-cell axes a, b, c (see Fig. 1) are inversely proportional to prime integers, h, k, l. They are called the Miller indices of the face. They are usually small because the corresponding lattice PLANES are among the densest and have therefore a high interplanar spacing and LOW indices.

If a-b = 2 and ab = 15 then find out a3-b3

Answer» HELLO !!



a - B = 2 ---------(1)



and,



a b = 15 -------(2)



From equation (1) we get,




a - b = 2


a = ( 2 + b ) ------(3)

Putting the value of a in equation (2)


a × b = 15


(2 + b ) × b = 15




b² + 2b - 15 = 0



b² + 5b - 3b - 15 = 0


b ( b + 5 ) - 3 ( b + 5 ) = 0



( b + 5 ) ( b - 3 ) = 0


( b -3 ) = 0 or ( b + 5 ) = 0


b = 3 or b = -15



Putting B = 3 in equation (3)



a = ( 2 + b ) = (2+3) = 5




----------------------------




( A³ - B³ ) = ( A - B )( A² + AB + B²)






( A³ - B³ ) = ( 2 ) [ ( 5)² + 15 + (2)² ]





( A³ - B³ ) = ( 2 ) × ( 44 )




( A³ - B³ ) = 88

Solve no 20...............

Answer»

According to QUESTION,
A and B can do a work in 12 days
∴ (A + B)’s one day’s work = 1 /12
Similarly, (B + C)’s one day’s work = 1/15
and (C + A)’s one day’s work = 1/20
On adding all three,

∴ 2 (A + B + C)’s one day’s work = 1/12+ 1/15 + 1/20
= 1/5
and (A + B + C)’s one day’s work = 1/10
∴ A, B and C together can complete the work in 10 days.

Area of a rectangular field is 560sq.metre.Ratio of their length &breadth is 5:7. Find the diagonal of a rectangle.

Answer»

Hey
SINCE the ratios are 5:7,then LET the sides be 5X and 7x.
560=5x*7x
560 = 35x²
560/35 = x²
16= x²
x = 4

Therefore the sides are:
5x = 5*4= 20m
7x = 7*4= 28m.

Let DIAGNOL be y
Therefore y = √(20² + 28²)
y = √(400 + 784 )
y = 35m (approx).

Hope it HELPS :))
