(9x quartic - 12x cubic + 54x Square) divided by 3x square

(9x quartic - 12x cubic + 54x Square) divided by 3x square

(9x^4-12x^3+54x^2)÷3x^2
=3x^2(3x^2-4x+18)÷3x^2
=3x^2-4x+18

If the cube of 4 / x = minus 216, then x=

x³/4=-216
x³=-216*4=-864=-6*6*6*4
X = - 6 * (4 cube)

The cube of 3 * 2 = 24, the cube of 3 * 2 equals 216, and the fourth power of - 2 * 3 equals 1296
(1)
3 * (cube of 2) = 24, the cube of (3 * 2) equals 216, the fourth power of (- 2 * 3) equals 1296, the square of (8 * 1 / 2) equals 16, the square of (8 * 1 / 2) equals 16, the square of (5 * 2) equals 100, the square of (5 * 2) equals 100, the square of (3) times (1 / 3) equals 1, and the square of (3 times 1 / 3) equals 1
All in all, what can you find?
(2.)
Can you find the result of (5 to the 100th power) multiplied by (0.2 to the 103rd power)?
（3.）
Calculate (2004 power of 4) times (2005 power of negative quarter)

2.5 ^ 100 * 0.2 ^ 103 = (5 * 0.2) ^ 100 * 0.2 ^ 3 = 0.008 3. The original formula = (4 * 1 / 4) ^ 2004 * (- 1 / 4) ^ 1 = - 1 / 4. ^ represents the index

Is the domain of (1-x) (x + 4) less than or equal to 0 negative 4 〈 x less than or equal to 1 or X1

The definition field should be a function term
(1-x) (x + 4) ≤ 0: X ≤ - 4 or X ≥ 1
