√44+5√99-3√11-√275
=√(2²×11)+5√(3²×11)-3√11-√(5²×11)
=2√11+5×3√11-3√11-5√11
=2√11+15√11-3√11-5√11
=√11(2+15-3-5)
=√11(17-8)
=9√11
[tex] \sqrt{44} +5 \sqrt{99} -3 \sqrt{11} - \sqrt{275} =2 \sqrt{11} +5 \cdot 3 \sqrt{11}-3 \sqrt{11} -5 \sqrt{11} = \\ =2 \sqrt{11} +15 \sqrt{11} -3 \sqrt{11} -5 \sqrt{11} =9 \sqrt{11} [/tex]
