Correct answer:सही उत्तर: (12)(12)
The exponent is (\left\lfloor\frac{80}{7}\right\rfloor+\left\lfloor\frac{80}{49}\right\rfloor=11+1=12). Add only up to powers of the prime.घात ( \left\lfloor\frac{80}{7}\right\rfloor+\left\lfloor\frac{80}{49}\right\rfloor=11+1=12) है। अभाज्य की घातों तक ही जोड़ें।
