3.30
Step-by-step explanation
remember

Step 1
set the equation
let x represents the unkown value, so.
x to the third power gives me 36:

Step 2
solve the equation
to solve the equation, we need to isolate x, hence
get the cubic root in both sides
![\begin{gathered} x^3=36 \\ \sqrt[3]{x^3}=\sqrt[3]{36} \\ x=3.301927249 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/onrbq1hd2f0kq57wrv19vavh8ae0dvxeoe.png)
so, the answer is 3.301927249
