x= -1,y =1 & z=2..
(xy+yz)² - 2x²y²z
= [(-1)(1) + 1(2)]2 - 2 (-1)2 (1)2 (2)2
= [-1 + 2]2 - 2 (4)
= (1)2 - 8
= 1 -8
= -7

perimeter = 13 cm b = 3 4/5 = 19/5 cm
Perimeter of rectangle = 2 length + 2 width
2l + 2(19/5) = 13
2l + 38/5 = 13
2l = 13 - 38/5
2l = (65 - 38)/5
2l = 27/5
l = 27/10

Let the number of winners =x
∴ Number of participants who are not winners = (63 - x)
∴ Prize money given to: Winners = x
Rs 100 = Rs 100 x
Non-winner participants = Rs 25 
(63-x)
= Rs 25 
63 - Rs 25x
= Rs 1575 - Rs 25x
According to the condition, we have
100x + 1575 - 25x = 3000
or 75x = 3000 - 1575 [Transposing 1575 to RHS]
or 75x = 1425
or x = 1425 
75 = 19
Thus, the number of winners = 19

12+(-13)+56+78+(-67)
= 12 -13 + 56 + 78 - 67
= -1 + 56 + 78 - 67
= 55 + 78 - 67
= 133 - 67
= 66

[17(2 - y) - 5(y + 12)]/(1 - 7y) = 8
34 - 17y - 5y - 60= 8(1 - 7y)
-22y - 26 = 8 - 56y
-22y + 56 y = 8 + 26
34 y = 34
y = 34/34
y = 1

Natural numbers that are squares of other natural numbers are called perfect square or square number.
For example;
We know that; 1 = 1²; 4 = 2²; 9 = 3²; 16 = 4²; 25 = 5² and so on.
Thus 1, 4, 9, 16, 25, etc., are perfect squares.
