Question

state if 3 root 71 is surd justify

Answer 1

Answer:

Step-by-step explanation:

The order of a surd indicates the index of root to be extracted. In n√a , n is called the order of the surd and a is called radicand.

A surd with index of root 3 is called  a third order surd or cubic surd

To justify ∛71 is surd

we have to make factorisation of 71, as we know 71 is a prime number and doesn't have factors other than 71 ,1

So its not possible to make factors of 71.

Hence it is a surd.
