What is the highest power of (2) that divides (20!)?(20!) को विभाजित करने वाली (2) की अधिकतम घात क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (18)(18)
The exponent is ( \left\lfloor\frac{20}{2}\right\rfloor+\left\lfloor\frac{20}{4}\right\rfloor+\left\lfloor\frac{20}{8}\right\rfloor+\left\lfloor\frac{20}{16}\right\rfloor=18 ). Add all quotients for a prime exponent.घात ( \left\lfloor\frac{20}{2}\right\rfloor+\left\lfloor\frac{20}{4}\right\rfloor+\left\lfloor\frac{20}{8}\right\rfloor+\left\lfloor\frac{20}{16}\right\rfloor=18 ) है। अभाज्य घात के लिए सभी भागफल जोड़ें।
