1: 60=2^2*3*5
280=2^3*5*7
=>BCNN(60;280)=2^3*5*7*3=840
2: 84=2^2*3*7
108=2^2*3^3
=>BCNN(84;108)=2^2*3^3*7=756
3: 13=13
15=3*5
=>BCNN(13;15)=13*3*5=195
4: 10=2*5
12=2^2*3
15=3*5
=>BCNN(10;12;15)=2^2*3*5=60
5: 8=2^3; 9=3^2; 11=11
=>BCNN(8;9;11)=2^3*3^2*11=72*11=792
6: 24=2^3*3
40=2^3*5
168=2^3*3*7
=>BCNN(24;40;168)=2^3*3*5*7=840

=>BCNN(30;105)=2*3*5*7=210

bn tự vẽ hình được nha
A) cos ot là tia phân giác của góc xoy
=> GÓC XOT = GÓC YOT = 60 ĐỘ : 2 = 30 ĐỘ
B) XÉT TAM GIÁC AOH VÀ TAM GIÁC BOH CÓ :
OB=OA(GT)
GÓC AOH = GÓC BOH ( OT LÀ TIA PHÂN GIÁC CỦA GÓC XOY )
OH CHUNG
=> TAM GIÁC AOH = TAM GIÁC BOH ( C-G-C)

a, không nhìn rõ
b, \(\dfrac{a+2\sqrt{a}+1}{a-1}\)
\(=\dfrac{\left(\sqrt{a}+1\right)^2}{\left(\sqrt{a}+1\right)\left(\sqrt{a}-1\right)}=\dfrac{\sqrt{a}+1}{\sqrt{a}-1}\)
đó đâu phải là hằng đẳng thức
