### Question

If P = 18, Q = 21, R = -6 and S = -4, Calculate $$\frac{(P- Q)^3 + S^2}{R^3}$$ + S2

### Options

A) $$\frac{-11}{216}$$

B) $$\frac{11}{216}$$

C) $$\frac{-43}{116}$$

D) $$\frac{43}{116}$$

### Explanation:

$$\frac{(P- Q)^3 + S^2}{R^3}$$ = $$\frac{(18 - 21)^3 + (-4)^2}{(-6)^3}$$
= $$\frac{-27 + 16}{R^3}$$
= $$\frac{-11}{-216}$$
= $$\frac{11}{216}$$

## Dicussion (1)

• $$\frac{(P- Q)^3 + S^2}{R^3}$$ = $$\frac{(18 - 21)^3 + (-4)^2}{(-6)^3}$$
= $$\frac{-27 + 16}{R^3}$$
= $$\frac{-11}{-216}$$
= $$\frac{11}{216}$$
