Answer 1

i donot know answer of this question

Answer 2

The correct answer is 44.

Given: $(7^{-1} -8^{-1} )^{-1} -(3^{-1} -4^{-1} )^{-1}$

To Find: Solve the equation and obtain final answer.

Solution:

$(7^{-1} -8^{-1} )^{-1} -(3^{-1} -4^{-1} )^{-1}$

Now, solving the first term.

= $(7^{-1} -8^{-1} )^{-1}$

= $\frac{1}{(7^{-1} -8^{-1} )}$

= $\frac{1}{\frac{1}{7}-\frac{1}{8} }$

= $\frac{56}{1}$

= 56

Now, solving the second term.

= $(3^{-1} -4^{-1} )^{-1}$

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

= $\frac{1}{\frac{1}{3}-\frac{1}{4} }$

= $\frac{12}{1}$

= 12

Now, subtract both the terms.

= 56 - 12

= 44

Hence, the final answer is 44.
