WebThis allows us to have a simple way of doing modular arithmetic: first perform the usual arithmetic, and then find the remainder. For example, to find 123 + 321 \pmod {11} 123+321 (mod 11), we can take 123 + 321 = 444 123+321 = 444 and divide it by 11, which gives us 123 + 321 \equiv 4\pmod {11}. 123+ 321 ≡ 4 (mod 11). Web14 Jun 2024 · Quotient of powers rule. Multiplication and division are opposites of each other -- much the same, the quotient rule acts as the opposite of the product rule. When dividing two bases of the same value, keep the base the same, and then subtract the exponent values. ... Zero power rule — Any base raised to the power of zero becomes one;

WebPowers can be used as a shorthand way of writing repeated multiplication of the same digits. 3 x 3 x 3 x 3 x 3 can be written as 3⁵. This is read as 'three to the power of five'. 1 of 4 7 x 7 x... WebRule 1: Product Rule The logarithm of the product is the sum of the logarithms of the factors. Rule 2: Quotient Rule The logarithm of the ratio of two quantities is the logarithm of the numerator minus the logarithm of the denominator. Rule 3: Power Rule The logarithm of an exponential number is the exponent times the logarithm of the base. WebCalculate the individual branch currents using the current division rule and find the equivalent circuit resistance. We can check our calculations as according to Kirchhoff’s Current Rule, all the branch currents will be equal to the total current, so: I T = I R1 + I R2 + I R3 = 10 + 4 + 1 = 15 amperes, as expected. tofex ug
