Answer:

x=\frac{-1\pm\sqrt{3}i}{2}

Step-by-step explanation:

f(x)=x^3-1

0=x^3-1

0=(x^2+2x+1)(x-1)

x-1=0

x=1 <-- Real Solution

x^2+x+1=0

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

x=\frac{-2\pm\sqrt{2^2-4(1)(1)}}{2(1)}

x=\frac{-1\pm\sqrt{1^2-4(1)(1)}}{2(1)}

x=\frac{-1\pm\sqrt{1-4}}{2}

x=\frac{-1\pm\sqrt{-3}}{2}

x=\frac{-1\pm\sqrt{3}i}{2} <-- Complex Solutions

\frac{4}{20} = <span>\frac{2}{e}

From there you can cross multiply to get rid of the denominators.

4e=2x20
4e=40
  e=10

There would be 10 ears.
