The evaluation of the expression given in surd form is 6.
Surds are expressions that use a root symbol, such as a square root, or another root symbol. Since the decimals of irrational numbers do not finish or recur, they cannot be expressed accurately in decimal form, hence surds are used instead.
Surds, in mathematics, are square root values that cannot be factored into a whole number or an integer. Numbers that are surds are irrational numbers.
From the given expression, the cube root of 216 can be computed as:
[tex]\sqrt[3]{216}[/tex]
Factor the number 216 as:
= [tex]\sqrt[3]{6^3}[/tex]
= 6
