I believe that you simplify it.

I have taken the second derivative, and now trying to find the zeroes of \[2+2x^-3\]

so obviously will then become\[2x^-3=-2\]

if I simplify the equation, then I get\[\frac{ 2 }{ x^3 }+2\]

but still not sure what to do to "get rid" of the exponent to leave x on it's own and find the value of x?

2 x^-3 = -2 divide both sides by 2 x^-3 = -1 1 / x^3 = -1 cross multiply - x^3 = 1 divide both sides by -1 x^3 = -1 x = -1
