99.99+99
=99.99+99.1
=99.(99+1)
=99.100
=9900
99 x 99 + 99
= 99 x 99 + 99 x 1
= 99 x ( 99 + 1 )
= 99 x 100
= 9900
99 x 99 + 99
= 9801 + 99
= 9900
Ai thấy đúng tk
Ai thấy sai sửa nhé
\(99\times99+99\)
\(=99\times\left(99+1\right)\)
\(=99\times100\)
\(=9900\)
\(99\times99+99\)
\(=99\times\left(99+1\right)\)
\(=99\times100\)
\(=9900\)
99 x 99 + 99 = 99 x ( 99+ 1 )
= 99 x 100
= 9900
99x99+99
=99x99+99x1
=99x(99+1)
=99x100
=9900
=9801+99
+9900
