If we
√6429 = 79.05061
but if we
81² = 6561
(80² = 6400, which is less than 6429)
∴ 6561 - 6429 = 132
∵ 132 must be added to 6429 to make it a perfect square.
And if we √6561 then we get 81.
√6429 = 79.05061
but if we
81² = 6561
(80² = 6400, which is less than 6429)
∴ 6561 - 6429 = 132
∵ 132 must be added to 6429 to make it a perfect square.
And if we √6561 then we get 81.
