Correct option is
A
44
Using law of exponents, a
−m
=
a
m
1
⇒ (7
−1
−8
−1
)
−1
−(3
−1
−4
−1
)
−1
=(
7
1
−
8
1
)
−1
−(
3
1
−
4
1
)
−1
⇒ (
56
1×8−1×7
)
−1
−(
12
1×4−1×3
)
−1
=(
56
8−7
)
−1
−(
12
4−3
)
−1
=(
56
1
)
−1
−(
12
1
)
−1
Again we will use a
−m
=
a
m
1
⇒(7
−1
−8
−1
)
−1
−(3
−1
−4
−1
)
−1
=(
56
1
)
−1
−(
12
1
)
−1
=56−12=44.
