I don't know that either is "simpler". They're more different notations (rational powers versus radicals) than simplifications of each other.which is simpler
x raised to 5/4 or x raised to the power of 5 inside a fourth root symbol (a square root with a 4)?
Why not? A fraction over a whole is just another number, right? Then you simplify or rearrange if you want a different format:Clearly I'm doing something wrong because the slope can't have a fraction over a denominator....
Wolfram Alpha still gives a complicated answer. Assuming your equation is right, then maybe the homework is expecting a numerical approximation instead of an algebraic solution.difference of probabilities-actual numbers are
e^(-.16x)-e^(-.2x)=.5 solve for x
Probably it's fine but the forum is for helping people with homework so I don't know if there's anybody who can help you write tests....probably later on in the future. I'll be looking for ideas for exam materials and such. Will that be okay?
