cube root of 216 = 6 > X= 6
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
9t + 15t= 216 24t=216 t=216/24 t=9
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.
216 = 216
2x2-y2
(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
