lets solve ~
[tex]\qquad \sf \dashrightarrow \: 3 \sqrt{50} \times \sqrt{22} [/tex]
[tex]\qquad \sf \dashrightarrow \: 3 \sqrt{2 \times 5 \times 5} \times \sqrt{2 \times 11} [/tex]
[tex]\qquad \sf \dashrightarrow \: 3 \sqrt{2 \times 2 \times 5 \times 5 \times 11} [/tex]
[tex]\qquad \sf \dashrightarrow \: 3 \times 2 \times 5 \times \sqrt{11} [/tex]
[tex]\qquad \sf \dashrightarrow \: 30 \sqrt{11} [/tex]
