Ta có :
\(A=75\left(4^{10}+4^9+...+1\right)+25\)
\(\Rightarrow A=75.4^{10}+75.4^9+....+75.4+75.1+25\)
\(\Rightarrow A=300.4^9+300.4^8+....+300+100\)
=> A chia hết cho 100

\(74.\) \(\left(2x-1\right)^3\)- \(5^2\)= \(7^{18}:7^{16}\)
\(74.\)\(\left(2x-1\right)^3\)\(-5^2\)= \(7^{18-16}\)
\(74.\)\(\left(2x-1\right)^3\)\(-25\)= \(7^2\)
\(74.\)\(\left(2x-1\right)^3\)\(-25\)= \(49\)
\(74.\)\(\left(2x-1\right)^3\)= \(49+25\)
\(74.\)\(\left(2x-1\right)^3\)= \(74\)
\(\left(2x-1\right)^3\)= \(74:74\)
\(\left(2x-1\right)^3\)= \(1\)
\(\left(2x-1\right)^3=1^3\)
\(2x-1=1\)
\(2x=1+1\)
\(2x=2\)
\(x=2:2\)
\(x=1\)
Vậy x = 1

đây là toán mà?
Ta có: 1/22< 1/1.2=1-1/2
1/32<1/2.3=1/2-1/3
..............................
1/1002< 1/99.100=1/99-1/100
Do đó: 1+1/22+1/32+...+1/1002< 1+1-1/2+1/2-1/3+....+1/99-1/100
=> 1+1/22+1/32+....+1/1002<1+1-1/100=2-1/100<2
nên 1+1/22+1/32+....+1/1002<2
Vậy 1+1/22+1/32+...+1/1002<2
