Question

simplify and express as a rational number
(6-¹ - 8-¹)-¹​

Answer 1

Answer:

We have,

(−1

5

/2

5

)=(−1×−1×−1×−1×−1)/(2×2×2×2×2)=(−1/32)

(2)

3

=(2×2×2)=8

(3

2

/4

2

)=(3×3)/(4×4)=(9/16)

Then,

=(−1/32)×8×(9/16)

=(−1×8×9)/(32×1×16)

By simplifying

=(−1×1×9)/(32×1×2)

=(−9/64)

Answer 2

Answer:

first we need to write it properly

(1/6-1/8)^-¹

then as we r subtracting we need to find out the LCM of 6 and 8=24

Then we will multiply 1/6with any number to get the denominator 24 we will do the same with 1/8 so

1/6×4/4=4/24 so the ans is 4

1/8×3/3=3/24 so the ans is 3

so

(4-3/24)^-¹=(1/24)^-¹

=so the final ans is 1/24 or 24
