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

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. – Ross Millikan Nov 15 '18 at 16:48

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