Answer 2

To evaluate the expression (1/3n - 1/12n) / (2/n^2) at n = -0.56, we substitute the value into the expression and perform the calculations:

Let's start with substituting n = -0.56 into the expression: (1/3(-0.56) - 1/12(-0.56)) / (2/(-0.56)^2)

Simplifying the numerator: (1/(-1.68) - 1/(-0.0672)) / (2/(-0.56)^2)

Finding the common denominator: (-0.595238 - (-14.880952)) / (2/(-0.56)^2)

Simplifying the numerator: (-0.595238 + 14.880952) / (2/(-0.56)^2)

Combining like terms: 14.285714 / (2/(-0.56)^2)

Simplifying the denominator: 14.285714 / (2 / 0.3136)

Dividing by a fraction is the same as multiplying by its reciprocal: 14.285714 * (0.3136 / 2)

Multiplying: 4.477366

Therefore, when n = -0.56, the value of the expression (1/3n - 1/12n) / (2/n^2) is approximately 4.477366.
