Step-by-step explanation:
732736
Step-by-step explanation:
A square is a flat shape with four equal sides; every angle is 90°.
Hence, a square with side length 856 has an area of 732,736.
856 squared equals the sum of the first 856 odd numbers:
\sum_{i=1}^{856} (2i-1) = 732,736∑
i=1
856 (2i−1)=732,736
In addition, the number can be calculated from 855 squared using the following identity:
n2 = (n − 1)2 + (n − 1) + n = (n − 1)2 + (2n − 1)
8562 = 8552 + 855 + 856 = 8552 + 1711 = 732,736
It can be also be computed from 855 squared with this identity:
n2 = 2 x (n − 1)2 − (n − 2)2 + 2
8562 = 2 x 8552 – 8542 + 2 = 2 x 731025 – 729316 + 2 = 732,736
The difference between the perfect square of 856 and its predecessor, 855, can be calculated with the identity n2 − (n − 1)2 = 2n − 1:
2 x 856 – 1 = 1711 = 8562 – 8552 = 732,736 – 731025 = 1711
856 is even, and the square numbers of even numbers are also even: (2n)2 = 4n2.
Squares of even numbers like 856 are divisible by 4 for \frac{(2n)^{2}}{4}
4 for (2n)²/4= n2.
