Question

Have an assignment due tonight and stuck on some questions. Please help? I am not sure of how to balance an equation that has a negative exponent?

Answer 1

I believe that you simplify it.

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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?

Answer 6

hi

Answer 7

what is your question?

Answer 8

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

great thank you
