What is the reverse of x = pow(y, 5)

math, objective-c

Solution

Try this (pseudo-code): `y = pow (x, 1.0 / 5);`

Problem

I must have a mental block, but I simply can't find the reverse of this math function: x = pow(y, 5); I have x and 5, how do I find y ? Here is a snip of my current code: ``` +(float) linearVolumeToVolumeCurve:(float)volume { return pow(volume, 5); } +(float) volumeCurveToLinearVolume:(float)volume { return ??? } ```
