= 9 x 9 + 25 x 9 + 33 + 2 x 9
= 9 x ( 9 + 25 + 2 ) + 33
= 9 x 36 + 33
= 324 + 33
= 357
k nha !!!!
9 x 9 + 25 x 9 + 33 + 18
= 9 x 9 + 25 x 9 + 33 + 2 x 9
= 9 x ( 9 + 25 + 2 ) + 33
= 9 x 36 + 33
= 357
\(9\times9+25\times9+33+18\)
\(=9\times9+25\times9+33+9\times2\)
\(=9\times\left(9+25+2\right)+33\)
\(=9\times36+33\)
\(=324+33\)
\(=357\)
= 9 . ( 9 + 25) + 33 + 18
= 9 . 33 + 33 +18
= 33 . 10 + 18
=330 + 18
= 348
9 x 9 + 25 x 9 + 33 + 18
= 18 + 25 x 9 + 33 + 18
= 18 + 225 + 33 + 18
= 243 + 33 + 18
= 276 + 18
= 294
Đáp số : 294
9 x 9 + 25 x 9 + 33 + 18 = (9 x 9) + (25 x 9) + (33 + 18)
= 81 + 225 + 51
= 306 + 51
= 357
Ai k mình mình k lại
tách 18=9*2
ta có 9*9+25*9+9*2+33
=9*(9+25+2)+33
=9*36+33
=324+33
=357
