98 × 98 + 98 + 98
= 98 × 98 + 98 × 1 + 98 × 1
= 98 × ( 98 + 1 + 1 )
= 98 × ( 99 + 1 )
= 98 × 100
= 9 800
98 x 98 + 98 + 98
= 9604 + 98 +98
= 9800
98x98+98+98
=98x98+98x1+98x1
=98x(98+1+1)
=98x100
=9800
Học tốt!
\(98\times98+98+98\)
\(=98\times\left(98+1+1\right)\)
\(=98\times100\)
\(=9800\)
_Chúc bạn học tốt_
98 × 98 + 98 + 98
= 98 × 98 + 98 × 1 + 98 × 1
= 98 × ( 98 + 1 + 1 )
= 98 × ( 99 + 1 )
= 98 × 100
= 9 800
hok tốt
98 × 98 + 98 + 98
= 98 × 98 + 98 × 1 + 98 × 1
= 98 × ( 98 + 1 + 1 )
= 98 × ( 99 + 1 )
= 98 × 100
