Question

BC(12; 16; 18) = ?

Answer 1

BC hay BCNN zậy bn??

Answer 2

Ta có :12=2^2*3 ; 16=2^4 ; 18=2*3^2

BCNN(12 ;16 ;18)=2^4*3=48

=>BC(12 ;16 ;18)={0;48;96;144;...}

Answer 3

khó quá duyệt đi

Answer 4

12 = 2^2 .3

16 = 2^4

18 = 2 . 3^2

BCNN = 2^4 . 3^2 = 144

BC(12; 16; 18) = 144; 288; 432; ...

Nếu thấy đúng tích nhaaa

 

Answer 5

Ta có: \(12=2^2.3\)

\(16=2^4\)

\(18=2.3^2\)

Ta có: \(BCNN\left(12,16,18\right)=2^4.3^2=144\) 

Vậy: \(BCNN\left(12,16,18\right)=144\)
