Question

$( {6}^{ - 1} - {8}^{ - 1} ) + ( {2}^{ - 1} - {3}^{ - 1} ) {}^{ - 1} evaluate$

Answer 1

$( {6}^{ - 1} - {8}^{ - 1} ) + ( {2}^{ - 1} - {3}^{ - 1} ) {}^{ - 1} \: \\ > > (\frac{1}{6} - \frac{1}{8} ) + (\frac{1}{2} - \frac{1}{3} )^{ - 1} \\ > > \frac{4 - 3}{24} + 2 - 3 \\ > > \frac{1}{24} - 1 \\ > > \frac{1 - 24}{24} = \frac{ - 23}{24}$

Answer 2

[(6)^-1 - (8)^-1] + [(2)^-1 - (3)^-1]^-1

[1/6 - 1/8] + [(2)^-1×-1 - (3)^-1×-1]

[1/6 - 1/8] + [(2)^1 - (3)^1]

[8 - 6/48] + [2 - 3]

[2/48] + -1

24 + (-1)
24 - 1
