Let’s do this in as much detail as possible, once and for all, so you can “see” it (with your mind's eye) exactly as you might have done it in your head:

(-3x)^2(-3x)^3

[(-3x)^2] [(-3x)^3]

[(-)(-)(3)(3)(x)(x)] [(-)(-)(-)(3)(3)(3)(x)(x)(x)]

[(+)(9)(x)(x)] [(-)(+)(27)(x)(x)(x)]

[(+)(-)(+) (9)(27) (x)(x)(x)(x)(x)]

[(-) (243) (x^5)]

-243x^5

9x^2 * -27x^3 = -243x^5
