x + x = 2x. Similarly, x^3 + x^3 = 2(x^3)
X = 2, 2 X 2 X 2 = 8 - 8 = 0
x3 - 4x = x(x2 - 4) = x(x + 2)(x - 2)
8 cubed = 8 x 8 x 8 = 512 512 = (5 x 100) + (1 x 10) + (2 x 1)
It is called two cubed It is number eight answer 2 x 2 = 4 4 x 2 = 8
2 x 2 x 2 = 2 cubed
It is x^2 + xy + y^2
64 x cubed minus y cubed is (4x - y)(16x^2 + 4xy + y^2)
Yes, 64 is 4 cubed. 4 x 4 x 4 = 64 Another way to look at it: 64 is 8 squared. 8 is a cubed number. 8 = 2 x 2 x 2. Therefore, 64 must be a cubed number: 2^2 x 2^2 x 2^2 = 8^2.
multiply the number by itself 3 times 2 cubed = 2 x 2 x 2 = 8 3 cubed = 3 x 3 x 3 = 27 4 cubed = 4 x 4 x 4 = 64 5 cubed = 5 x 5 x 5 = 125 etc.
x^3 + y^3 = (x + y)(x^2 - xy + y^2)
2 x 2 x 2 x 5 x 5 x 5 x 11 = 11,000 2 cubed times 5 cubed times 11 = 11,000
2 * 2 * 2 * 2 * 2 * x * x * x
A number multiplied by itself thrice. 2 x 2 x 2 equals 2 cubed.
x + x = 2x. Similarly, x^3 + x^3 = 2(x^3)
2 x 2 x 2 = 8
23 x 53 = 1,000
