Number of strings =

= 21 x 21 x 21 x 21 x 21 x 5 = 20 420 505
Answer: 20 420 505
let the 2 integers be x and x + 2.
so we have the equation:-
3(x + 2) = x - 10
3x + 6 = x - 10
2x = -16
x = -8
the integers are -8 and -6 answer
(3 1/2+8 2/3)-3 5/6
= 1.898717
(10 1/4 - 5 5/8)-1 3/8
= -5.221721
(2 2/3+ 4 5/6)+3 3/8
= 9.795734
The square root of 64 is 8 because 8x8 is 64
