Answer:

$(m^{4} + 5) - n^{3}$ = 85

Step-by-step explanation:

$(m^{4} + 5) - n^{3}$ given m = - 2, and n = -4

Substitute the given values into the polynomial expression:

$(m^{4} + 5) - n^{3}$

$[(-2)^{4} + 5] - (-4)^{3}$

= (16 + 5) - (-64)

= 21 + 64

= 85

Therefore, the correct answer is 85.

Answer:

The trigonometric equation (sin Θ − cos Θ)^2 − (sin Θ + cos Θ)^3 can be simplified by:Using x for Θ: (sinx - cosx)^2 - (sinx + cosx)^2 = (sin^2 x - 2sinxcosx + cos^2 x) - (sin^2 x + 2sinxcosx + cos^2 x) = - 2 sinx cosx - 2 sinx cosx = - 4 sinx cosx = - 2sin(2x)
