We have:
[tex]4*\sqrt[3]{81}[/tex]
and we know that [tex]81=3^4[/tex], don't we?
therefore Let's replace it.
[tex]4*\sqrt[3]{3^4}[/tex]
and we can write this value like this [tex]3^4=3^3*3^1[/tex]
them, let's replace
[tex]4*\sqrt[3]{3^3*3^1}[/tex]
we can take out [tex]3^3[/tex], them we obtain
[tex]4*3*\sqrt[3]{3^1}[/tex]
[tex]\boxed{\boxed{4*\sqrt[3]{81}\equiv12*\sqrt[3]{3}}}[/tex]

We have 4 x ∛81
now, we simplify ∛81.
we know that 81 = 9 x 9
9 = 3 x 3.
Thus, ∛81 becomes ;
∛3 x 3 x 3 x 3
= ∛3 x 3 x 4
= 12 x ∛3 ( ; is equivalent to 4 x ∛81)
