A = 338350 x 2
A= 676700
vậy A p=676700
chúc em học tốt
Tacó A=22x42x62x…x2002
A=(1x2)2x(2x2)2x(3x2)2x…x(100x2)2
A=12x22x22x22x32x22x…x1002x22
A=12x4x22x4x32x4x…1002x4
A=4.(12x22x32x…x1002)
A=4.338350
A=1353400
Vậy A=1353400
ta có : \(2^2.\left(1^2+2^2+3^2+...+100^2\right)=2^2.338350\)
\(\Rightarrow2^2+4^2+6^2+...+200^2=1353400\)
vậy \(A=1353400\)
Ta có A= 22+42+62+...+2002
= 22.(1+22+32+...+1002)
= 4.338350
=1353400
