Số hạng tổng quát trong tổng trên: \(n^3\)

Nhận xét: \(n^3-n=n\left(n^2-1\right)=\left(n-1\right).n\left(n+1\right)\)

\(\Rightarrow\) \(n^3=\left(n-1\right)n\left(n+1\right)+n\)

áp dụng ta có:

\(1^3=0+1\)

\(2^3=1.2.3+2\)

\(3^3=2.3.4+3\)

...................

\(100^3=99.100.101+100\)

\(\Rightarrow\) A= ( 1+2+3+.........+100) + ( 1.2.3+2.3.4+........+99.100.101)

Ta có : B = 1.2.3+2.3.4+..............+99.100.101

4B = 1.2.3.4+2.3.4.(5-1)+............+ 99.100.101.(102-98)

4B= 1.2.3.4+2.3.4.5-1.2.3.4+............+99.100.101.102-98.99.100.101

4B-B= 99.100.101.102 \(\Rightarrow\) B= 99.100.101.102 : 3=33996600

C = 1 + 2+3 + ...+ 100 = ﴾1+100﴿.100 : 2 = 5050

Vậy A = C + B = 33996600+5050+34001650

I don't have enough time(finish) TO FINISH my work yesterday.

\(\frac{a+5}{a-5}=\frac{b+6}{b-6}\Rightarrow\left(a+5\right)\left(b-6\right)=\left(a-5\right)\left(b+6\right)\Rightarrow a.b+5.b-6a-30=a.b-5.b+6.a-30\Rightarrow a.b+10.b=a.b+12a\)\(\Rightarrow10.b=12.a\Rightarrow5.b=6.a\Rightarrow\frac{a}{b}=\frac{5}{6}\left(đpcm\right)\)
