4x * x = 4x^2
64 is the cube of 4 so: x3 + 64 = (x + 4)(x2 - 4x + 16)
Four times a number x equals 4x.
x = number Four times the number (4x) is the same as the number increased by 78 (x + 78). Since they are both equal, then 4x = x + 78 4x - x = 78 3x = 78 x = 26
x3 + 4x
4x
4x * x = 4x^2
4x^4 or 4x*4x*4x*4x A formula would be (x^a)(x^b)= x^a+b x^a) / (x^b)= x^a-b
64 is the cube of 4 so: x3 + 64 = (x + 4)(x2 - 4x + 16)
2x times 4x is 8x squared- then that times x is 8x to the power of three.Mathmatically represented as 8x^3
Four times a number x equals 4x.
5.76899828 orFactor the 192:=8x24=8 x 8 x 3remember that cube root of 8 is 2, so you have:2 x 2 (cube root of 3) = 4 cube root of 3for the x^9, cube root is x^(9/3) = x^3final answer:4x^3(cube root 3)that's' it! ;)
4x^2
The volume of a cube is the length of an edge times itself and times itself again. X= Length of an edge Volume is X*X*X or X3
cube.
4x
4x - 6 = 22 Therefore, 4x = 28 x = 28/4 x = 7
