\huge{\texttt{SOLUTION:-}}

A surd is an irrational number . It is any number that includes a radical symbol " √ " and cannot be calculated exactly.

\huge{\texttt{SURD\: LAWS:-}}

 \sqrt{a}  \times  \sqrt{b} \:  =  \sqrt{ab} \\  \frac{ \sqrt{a} }{ \sqrt{b} }  =  \sqrt{ \frac{a}{b} }  \\  \sqrt{ {a}^{2} }  = a \\

eg. (i)

 \sqrt{50 \: }  =  \sqrt{25}  \times  \sqrt{2}

HERE , IN YOUR QUESTION , YOU ASKED WHETHER √49 IS A SURD OR NOT.

√49 = 7

-->>AS THIS IS A RATIONAL NUMBER AND THE VALUE IS EXACT NUMBER , THIS ISN'T A SURD.
