100 x 100 - 10 + 100
= 10 000 - 10 + 100
= 9 990 + 100
= 10 090
~~~ nha bn ~~~
100 x 100 - 10 + 100
= 10000 - 10 + 100
= 9990 + 100
= 10090
số đó là
100x100-10+100
=10000-10+100
=10090
néh bn
100 x 100 - 10 + 100 = 100 x 99 - 10
= 9900 - 10
= 9890
k nha
\(100.100-10+100\)
\(=10000-10+100\)
\(=9990+100\)
\(=10090\)
chuc bn hoc gioi!
