I'm working through a textbook and one question is:




Use a calculator to find the value of the following expression: $$sqrt[large4]{3^3}$$




The textbook answer is given as $2.2795$; however, using https://live.sympy.org/, if I enter root(3**3, 4), I get back 3^3/4.



How do I arrive at $2.2795$?





Here's the original question and the given solution:

  • When I put it into simpy it is clearly $3^{(frac 34)}$ as it should be.

$3^{frac{3}{4}}$ is what you get out. Not $frac{3^3}{4}$. As it happens, $3^frac{3}{4}$ is approximately 2.2795.
