Simplifying formulas
WebbExample. Say we wish to simplify the expression: 3 + log2(5) Then the trick is to write 3 as a logarithm in base 2 and then use the addition rule to simplify . Using the result, written above, we can state: 3 = log2(23) And so we can rewrite and simplify the expression as follows: 3 + log2(5) = log2(23) + log2(5) = log2(8) + log2(5) = log2(8 × ... WebbFactoring formulas are used to factorize expressions depending upon their forms. The terms in expression can be compared with a suitable factoring formula to factorize. What Is the Factoring Formula For Difference of Cubes? The factoring formula for difference of cubes is given as, x 3 - y 3 = (x - y) (x 2 + xy + y 2).
