Answer 2

Answer:

4)2 5)2.25 6)≈0.0260122949

Step-by-step explanation:

4)$(1/3)^{-1} + (1/5)^{-1} - (1/6)^{-1}$

= $(3/1)^{1} + (5/1)^{1} - (6/1)^{1}$

= $3 + 5 - 6$

= $2$

5)$(2/3)^{-2} * (-7/8)^{0}$

= $(3/2)^2 * 1$

= $2.25 * 1$

= $2.25$

6)$(2/3)^{-3} * (5/6)^{0}$

= $(3/2)^{3} * 1$

= $1.5^{3} * 1$

= $3.375 * 1$

= $3.375$

$(a/b)^{-3} = 3.375^{-3}$

= $1/3.375^{3}$

= $1/38.4433594$

≈ $0.0260122949$
