Penjelasan dengan langkah-langkah:

buktikan

[tex]\sf \sum\limits_{j =1}^n (3j+2)^2 = 9 \sum\limits_{j =1}^n j^2 + 12 \sum\limits_{j =1}^n J + 4(n)[/tex]

akan di buktikan ruas kiri =  ruas kanan

[tex]\sf ruas\ kiri\ \sum\limits_{j =1}^n (3j+2)^2=[/tex]

[tex]\sf = \sum\limits_{j =1}^n (9j^2 +12 j+ 4)[/tex]

[tex]\sf = 9 \sum\limits_{j =1}^n j^2 + 12 \sum\limits_{j =1}^n J + 4\sum\limits_{j =1}^n (1)[/tex]

[tex]\sf = 9 \sum\limits_{j =1}^n j^2 + 12 \sum\limits_{j =1}^n J + 4(n)[/tex]
ruas kiri = ruas kanan
terbukti
