The above shows the issue. ans1 shows the default output of the expression. ans2 shows that vpa() is not computing the variable point number for the expression. ans 2_5 shows what it should be computing to. The result I'm looking for is x^0.182.
ans3 just shows that vpa() produces the expected result when the function is multiplication--it's something in the exponent that's tripping it up.
How can I request that the exponent be evaluated by vpa?
