\(10\cdot10=100\)

\(100\cdot100=10000\)

Tính:

10*10=100

100*100=10000

1000*1000=1000000

10000*10000=100000000

100000*100000=10000000000

1000000*1000000=1000000000000

10000000000*10000000000=100000000000000000000

\(\frac{1}{10}+\frac{20}{100}+\frac{300}{1000}+\frac{40000}{100000}\)

\(=\frac{1}{10}+\frac{20}{10}+\frac{30}{10}+\frac{40}{10}\)

\(=\frac{1+2+3+4}{10}\)

\(=\frac{10}{10}\)

\(=1\)

1/10 + 20/100 + 300/1000 + 4000/10000

=1/10 + 2/10 + 3/10 + 4/10

=10/10

=1

\(\frac{1}{10}+\frac{20}{100}+\frac{300}{1000}+\frac{4000}{10000}\)

\(=\frac{1}{10}+\frac{2}{10}+\frac{3}{10}+\frac{4}{10}\)

\(=\frac{1+2+3+4}{10}\)

\(=\frac{10}{10}\)

\(=1\)

10+100+1000+10000+25= 11135

tk nhé

10 + 100 + 1000 + 10000 + 5²

= 10 + 100 + 1000 + 10000 + 25

= 11135

Bài 1 :a,

\(17\frac{61}{100}=17+\frac{61}{100}=17+0,61=17,61\)

\(31\frac{501}{1000}=31+\frac{501}{1000}=31+0,501=31,501\)

\(30\frac{32}{100}=30+\frac{32}{100}=30+0,32=30,32\)

\(24\frac{7}{10}=24+\frac{7}{10}=24+0,7=24,7\)

\(18\frac{27}{10000}=18+0,0027=18,0027\)

b, \(5\frac{3}{10}=5+\frac{3}{10}=5+0,3=5,3\)

\(51\frac{62}{100}=51+\frac{62}{100}=51+0,62=51,62\)

\(90\frac{8}{100}=90+\frac{8}{100}=90+0,08=90,08\)

\(35\frac{3}{1000}=35+\frac{3}{1000}=35+0,003=35,003\)

A= 9/10 + 99/100 + 999/1000 + 9999/10000

4 - A =(1 - 9/10 ) + ( 1 - 99/100 ) + (  1 - 999/1000 ) +( 1 - 9999/10000 )

4 - A = 1/0 + 1/100 + 1/1000 + 1/10000

4 - A = 1/10 - 1/10000

4 - A = 0.0999

A = 4 - 0.0999

A = 3.9001
