I'm confused because of the exponents rules. please show me the steps in simplifying the exponents then taking the derivative.

**drwls**, Tuesday, October 23, 2007 at 3:07amFirst lets break it up into terms that can be differentiated separately.

(x^2(2+x^1/2))/x^4

=[2x^2 + x^(5/2)]/x^4

= 2x^-2 + x^(-3/2)

Now use the x^n exponent derivative rule

df/dx = -4x^-3 -(3/2)x^(-5/2)
