Weblog b (3 ∙ 7) = log b (3) + log b (7) The product rule can be used for fast multiplication calculation using addition operation. The product of x multiplied by y is the inverse logarithm of the sum of log b ( x) and log b ( y ): x ∙ y = log -1 (log b … Web(a−b) 2 = a 2 − 2ab + b 2. If you want to see why, then look at how the (a−b) 2 square is equal to the big a 2 square minus the other rectangles: (a−b) 2 = a 2 − 2b(a−b) − b 2 = a 2 − 2ab + 2b 2 − b 2 = a 2 − 2ab + b 2. 3.
