987 = 9 . 102 + 8 . 10 + 7;
2564 = 2 . 103 + 5 . 102 + 6 . 10 + 4;
abcde = a . 104 + b . 103 + c . 102 + d . 10 + e
987 = 9 . 102 + 8 . 10 + 7;
2564 = 2 . 103 + 5 . 102 + 6 . 10 + 4;
abcde = a . 104 + b . 103 + c . 102 + d . 10 + e
987=9.100+8.10+7 nghĩa là :
987=9.10^2+8.10^1+7.10^0
2564=2.10^3+5.10^2+6.10^1+4.10^0
abcde=a.10^4+b.10^3+c.10^2+d.10^1+e.10^0
987 = 9 . 102 + 8 . 10 + 7;
2564 = 2 . 103 + 5 . 102 + 6 . 10 + 4;
= a . 104 + b . 103 + c . 102 + d . 10 + e
Ta có: 987 = 100.9+10.8+7
= 10\(^2\).9+10\(^1\).8+10\(^0\).7
2564= 1000.2+100.5+10.6+4
=10\(^3\).2+10\(^2\).5+10\(^1\).6+10\(^0\)+4
\(\overline{abcde}\)= 10000.a+1000.b+100.c+10.d+e
=10\(^4\).a+10\(^3\).b+10\(^2\).c+10\(^1\).d+10\(^0\).e
\(987=10^2.9+10^1.8+10^0.7\)
\(2564=10^3.2+10^2.5+10^1.6+10^0.4\)
\(\overline{abcde}=10^4.a+10^3.b+10^2.c+10^1.d+10^0.e\)
987=10 mu 2.9+10 mu1.8+10mu 0.7
2564= 10 mu 3. 2+ 10 mu 2.5 +10 mu 1 .6+ 10 mu 0 . 4
