Step-by-step explanation:
6miles= 9656.064 metres
20 and 0 = largest sum of squares
10 and 10 = smallest
11/3 would be closlely to 3.5 because it is 3.66667
3y^-4 × (2y^-4) = 6y^-8
= 6/1/y^8
= 6/y^8
.................................................
1) When x^1 multiply with x^2, 1 will add to 2 and become 3
= x^3
2) y^-1 = 1/y
3^-2 = 1/3^2 = 1/9
5^-2 = 1/5^2 = 1/25
