Is the 4th root of $3^3$ $3^3/4$ or $2.2795$?

50 Views Asked by At

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 $2.2795$?

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