2/Tính Giá Trị Biểu Thức 

( 158 + 144 ) × 32 - 284

4510 - 225 + ( 198 + 81 × 21 )

83489 - 75 × 26

Answer 1

(158 + 144) x 32 - 294 = 302 x 32 - 294 = 9664 - 294 = 9370

4510 - 255 + (198 + 81 x 21) = 4510 - 225 + (198 + 1701) = 4285 + 1899 = 6184

83 489 - 75 x 26 = 83 489 - 1950 = 81 539

Answer 2

=9380.

=6184.

=81539.

Answer 3

(158+144)x32-284

=302x32-284

=9664-284

=9380

4510-225+(198+81x21)

=4510+(198+1701)

=4510+1899

=6409

83489-75x26

=83489-1950

=81539

Answer 4

\(\left(158+144\right).32-284\)

\(=302.32-284\)

\(=9664-284\)

\(=9380\)

\(4510-225+\left(198+81.21\right)\)

\(=4285+1899\)

\(=6184\)

\(83489-75.26\)

\(=83489-1950\)

\(=81539\)
