Question :-

(3 {}^{ - 1}  + 2 {}^{ - 1} ) {}^{ - 2}    \div (5 {}^{ - 1}  + 6 {}^{ - 1} ) {}^{ - 1}

Solution :-

(3 {}^{ - 1}  + 2 {}^{ - 1} ) {}^{ - 2} \div (5 {}^{ - 1}   + 6 {}^{ -1 } ) {}^{ - 1}

Apply formula

(x {}^{ -a} ) =  \frac{1}{x {}^{a} }

Hence,

( \frac{1}{3}  +  \frac{1}{2} ) {}^{ - 2}  \div ( \frac{1}{5}  +  \frac{1}{6}) {}^{ - 1}   \\  \\  \\ ( \frac{2 + 3}{6} ) {}^{ - 2}  \div ( \frac{6 + 5}{30} ) {}^{ - 1}  \\  \\  \\ ( \frac{5}{6} ) {}^{ - 2}   \div ( \frac{11}{30} ) {}^{ - 1}  \\  \\  \\

Apply formula

( \frac{x}{y} ) {}^{ - n}  = ( \frac{y}{x} ) {}^{n}

So,

( \frac{6}{5} ) {}^{2}  \div ( \frac{30}{11} ) {}^{  1}  \\  \\  \\ ( \frac{36}{25} ) \times ( \frac{11}{30} ) \\  \\  \frac{66}{125}  \:  \:  \:  \: ans

Thanks!
