Question

Cat e (2√2+3√3)la a 2 prin formula (a+b)2=a2+2ab+b2 nu imi iese multumesc☺

Answer 1

$(2 \sqrt{2} +3 \sqrt{3} )=(2 \sqrt{2} )^2+2 \cdot 2 \sqrt{2} \cdot 3 \sqrt{3} +(3 \sqrt{3} )^2= \\ =8+12 \sqrt{6} +27=35+12 \sqrt{6}$

Answer 2

$(2 \sqrt{2}+3 \sqrt{3})^{2}=(2 \sqrt{2})^{2} +2*2 \sqrt{2}*3 \sqrt{3} +(3 \sqrt{3})^{2} =2*4+12 \sqrt{6}+9*3 =$$=35+12 \sqrt{6}$
