Derivatives

[apple77]

Hi,

How can I convert this equation: Q=7.489 * P^-1.27
into Q/P = ?

this is not exponent but derivatives rule...

There's no calculus on the GMAT, you'll never need to use derivatives.

As Stuart says, there's no calculus on the GMAT, so this is for interest only - GMAT test takers can ignore the following!

The derivative of c*x^m is c*m*x^(m-1). So if y = 7.489*x^(-1.27), then dy/dx = 7.489*(-1.27)*x^(-2.27).
