$b)x=\sqrt[3]{36}$

Step-by-step explanation

$\begin{gathered} x^3=36 \\ \end{gathered}$

to solve an equation we need to isolate the variable, in this case, x, so

Step 1

remember this property of the radicals

$\sqrt[m]{a}=a^{(1)/(m)}$

hence

a) get the cubic root in both sides of the equation

$\begin{gathered} x^3=36 \\ \sqrt[3]{x^3}=\sqrt[3]{36} \\ x^{(3)/(3)}=\sqrt[3]{36} \\ x=\sqrt[3]{36} \end{gathered}$

therefore, the answer is

$b)x=\sqrt[3]{36}$

I hope this helps you
