Question

Helppp ppleasee ??!!

Answer 1

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 2

Answer: 85

Step-by-step explanation:

(m^4+5)-n^3

(-2^4+5)-(-4)^3

(16 + 5)-(-64)

21 + 64 = 85
