Consider the expression. Note that: Based on the example above, we can conclude that: To elevate a product to an exponent, we must elevate each factor to that exponent. Generically: Next: Distributive in relation to division

To solve complete equations of the 2nd degree we will use the Bhaskara formula. From the equation, where a, b, c IR e, we will develop step by step the deduction of the Bhaskara formula (or solving formula). Step 1: We will multiply both members by 4 a. 2nd step: pass 4 ac to 2nd member.

If we multiply the number 12345679 by any multiple of 9, between 9 and 81, we get a product whose repeating digit is the multiplier itself divided by 9. 12345679 x 9 = 111.111.111 (9/9 = 1) 12345679 x 18 = 222,222,222 (18/9 = 2) 12345679 x 27 = 333,333,333 (27/9 = 3) 12345679 x 36 = 444.
