Question

((3/4)^{-1} - (1/4)^{-1})^{-1}

Answer 1

Step-by-step explanation:

• $( \frac{3}{4} ) {}^{ - 1} - ( (\frac{1}{4} {})^{ - 1} ) {}^{ - 1}$
• $= > \frac{4}{3} - ( \frac{1}{4} ) {}^{( - 1)( - 1)}$
• $= > \frac{4}{3} - \frac{1}{4}$

$= > \frac{16 - 3}{12}$

• $\frac{13}{12}$
• Hence the required answer. I hope it will help you. Thank you
