The first two statements are correct.
6(-2)^3 - 2(-6) = 6(-8) + 12 = -48 + 12 = -36, so that's right too.

-5^4=-625 is right
(-5)^4=+625 is right
6w^3 -2x for w= -2 and x= -6= -36 is right
hope this helped

The first two are right.
[6(-2)]^3 -2(-6) = (-12)^3 +12 = -1,728+12 = -1,716
OR
6 (-2)^3 - 2(-6) = 6(-8) + 12 = -36
Depending on whether the ^3 is including the 6 or not. It's kind of ambiguous the way you typed it.

Yes, -(5^4) = -625
Yes, (-5)^4 = +625
Yes,
6w³ - 2x = -36 for [ w=-2; x=-6 ]

no longer too undemanding algebra yet do no longer hassle ask your instructor for some help. i take advantage of the FOIL approach -- First, Outer, inner, final 2 (x+3)(x+5) = 2 (x*x + x*5 +x*3 +3*5)= 2 (x^2 +8x +15) = 2x^2 + 16x + 30 <----- perfect answer. 2d answer => (- 3x)(4y²)(12x²y) = (- 3x)(48x²y³) = - 144x³y³ answer: - 144x³y³
