Hey there !

Surd : Let n be a positive integer and a be a rational number ,

if a^1/n is not a rational number,

that is not a power of any number to exponent "n " ,

then a^1/n is called a surd of nth order .

Order of the surd a^1/n is n .

So,

 \sqrt[3]{ \sqrt[2]{5} } \\ = \sqrt[6]{5}

We observe that ,
 \sqrt[3]{ \sqrt[2]{5} }

is a surd of order 6 .

So ,The correct answer is Option C , 6

Option ( C ) is correct.


Cube root of √5


= (5½ )^⅓


= 5^( 1/2 × 1/3 )


= 5^1/6


Degree is 6.
