SUMMARY

The forum discussion centers on the integration of the expression e^(x^(5/3)). The user correctly identifies that the integral of x^(5/3) is (3/8)x^(8/3) but is uncertain about how to approach the integration of the entire expression involving the exponential function. The community suggests clarifying whether the expression is (e^x)^(5/3) or e^(x^(5/3)), with the latter being significantly more complex and likely unsolvable using basic calculus techniques. The TI-89 calculator struggles with this problem, and Maple provides unhelpful output.

PREREQUISITES
  • Understanding of integral calculus, specifically integration techniques.
  • Familiarity with exponential functions and their properties.
  • Knowledge of mathematical notation and interpretation of expressions.
  • Experience using graphing calculators like TI-89 or software like Maple for calculus problems.
NEXT STEPS
  • Research advanced integration techniques for complex functions.
  • Learn about the properties of exponential functions in calculus.
  • Explore symbolic computation software capabilities, particularly Maple.
  • Study substitution methods in integration for handling composite functions.
USEFUL FOR

Students in calculus courses, educators teaching integration techniques, and anyone seeking to understand complex integration problems involving exponential functions.

Homework Statement


Hello, I am struggling with an integration problem.

e ^ x ^ (5/3)

Homework Equations



Um.

The Attempt at a Solution



So I know the integral of x^(5/3) is (3/8)x^(8/3). But when I am trying to integrate the whole thing, with e in it, do I just treat x^(5/3) like a constant? Or do I still have to integrate it?

Possible solutions: e^x^(5/3)
or
e^(3/8)x^(8/3)
or
something else... please help...

Take a close look at the problem. Does it appear to be (e^x)^(5/3) or is it e^(x^(5/3))?

The first is relatively easy (simplify and substitute). If in doubt, I'd assume this interpretation.

The second is really, really ugly. I can't figure out how to do it, my TI-89 chokes on it, and Maple spits out the following gibberish:

so I'm guessing it's not really solvable by hand using first/second-year calculus techniques.
