Answer: (x - 2)(x² + 2x + 4)
Factor the difference of cubes:
a³ - b³ = (a - b)(a² + ab + b² )
note 8 = 2³ = 8 ⇒ b = 2 , with a = x
So
x³ - 8
= x³ - 2³
= (x - 2)(x² + 2x + 2²) = (x - 2)(x² + 2x + 4)
true
No, milli and centi are meaningful prefixes. Milli means 1/1000 and centi means 1/100. So by this there are 10mm in a cm. Now you are talking about volume and volume cubes the units, but this alco cubes the difference between cm and mm. so 10x10x10 is the difference (i.e. 1000) between cm^3 and mm^3. So 10mm^3 would actually be 0.01cm^3 and 10cm^3 would be 10,000mm^3.
That means that you calculate the cubes of two numbers, and then either add or subtract them.
Sum and difference of two cubes is factored this way : a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
The cube root of the expression 403 is 40 itself. This follows from the definition of cubes and cube roots.

true.
That's either the sum or difference of two cubes.
Perfect cubes.
4cubes times 2 cubes=8cubes
The volume of cylinders are measured in cubic units.
7 cubed is 343
Example 14 sugar cubes.
The answer depends on the value of m. The expression is a multiple of a difference of two cubes and so can be factorised quite easily but the question is not about factorising.
The answer is elementary my dear. If you want to mahe cubed stakes, you make meat cubes first, then grill them like a steak. Alternatively, start to groll steaks first, then halfweay through cut them into cubes before continuing to groll them. That way you get two-coloured cubed stakes.
153 cubed is 3581577. And the sum of one number is itself.
