Answer:

It's a surd.

Step-by-step explanation:

On multiplying √50 and √162 you get the answer as √8000 and on finding the factors it comes out to be 40√5 which is a surd.

\sqrt{50}  \times  \sqrt{162}  \\  \\  =  \sqrt{50 \times 162}  \\  \\  =  \sqrt{5 \times 5 \times 2 \times 2 \times 3 \times 3 \times 3 \times 3}  \\  \\  =  \sqrt{25 \times 4 \times 9 \times 9}  \\  \\  = 5\sqrt{4 \times 9 \times 9}  \\  \\  =  (5 \times 2)\sqrt{9 \times 9}   \\  \\  = 10 \sqrt{9 \times 9}  \\  \\  = 10 \sqrt{81}  \\  \\  = 10 \times 9 \\  \\  =    \green{\boxed{90}}

Hence, the value of √50 × √162 = 90 is a rational number therefore, √50 × √162 is not a surd.
