5x3 = 320 x3 = 320/5 = 64 So x = cuberoot(64) = 4

y2=x3+3x2

K = 6

Example: 4*216 = 864

147x3 = 441 x3 = 441/147 x3 = 3 x = 31/3 x ≈ 1.4

Realising that 125 is a perfect cube, this is actually pretty easy: x3 + 125 = 0 x3 = -125 x = -5

x5 = x3 times x2. In this case x3 = 64 so x = cube root of 64 ie 4

Suppose x3-4x = 0. To solve, factor: x3-4x = x(x2-4) = x(x+2)(x-2) = 0 Now, a product equals 0 if and only one or more of the factors equals 0, so set each factor to 0 and solve. The roots are 0,-2 and +2.

(x - 6)(x2 + 6x + 36)

X3xX4=X3+4=X7 this is the correct answer.

216/12 equals 18 feet.

3 ln(x) = ln(3x)ln(x3) = ln(3x)x3 = 3xx2 = 3x = sqrt(3)x = 1.732 (rounded)

63 = 216

5x3 = 320 x3 = 320/5 = 64 So x = cuberoot(64) = 4
