plz solve it fast its urgent.​

Answer 1

Step-by-step explanation:

$\frac{ ( - \frac{1}{2}) {}^{ - 3} }{ ( - \frac{1}{2}) {}^{ - 4} } - \frac{ ( - \frac{1}{2}) {}^{ - 5} }{ ( - \frac{1}{2}) {}^{ - 6} } \\ \\ = ( - \frac{1}{2} ) {}^{ (- 3 - ( - 4))} - ( - \frac{1}{2} ) {}^{( - 5 - ( - 6))} \\ \\ = ( - \frac{1}{2} ) {}^{ - 3 + 4} - ( - \frac{1}{2} ) {}^{ - 5 + 6} \\ \\ = ( - \frac{1}{2} ) {}^{1} - ( - \frac{1}{2} ) {}^{1} \\ \\ = - \frac{1}{2} + \frac{1}{2} \\ \\ = 0 \\ \\ \\ formula \: \: \: - \: \: \: ( \frac{x {}^{m} }{x {}^{n} }) = x {}^{ m- n}$
