Thank you very much
Rewrite the expression as..
y = -2/x²
= -2x^(-2)
Hence, by power rule d/dx xⁿ = nx^(n - 1)...
dy/dx = -2(-2x^(-2 - 1))
= 4x^(-3)
= 4/x³
I hope this helps!
I hate x in the denominator, so move it to the numberator 1st. then you have ( -2x^(-2) ). Then follow the same rules: bring the exponent out in front and lower the exponent by 1. d/dx = 4 x^(-3)
4 / x^3
