Trả lời:
(-65)-(-37)
= (-65)+37
=-28
(-159)-280:(-7)
=(-159)-(-40)
=(-159)+40
=-119
(-12).\(3^2\)+240:\(\left(-2\right)^2\)
=-108+60
=-48
\(5.\left(-2\right)^3-36:3^2\)
=\(-40-4\)
=\(-44\)
\(128-\left[68+8.\left(35-37\right)^2\right]:\left(-4\right)\)
=\(128-\left[68+8.4\right]:\left(-4\right)\)
=\(128-\left[68+32\right]:\left(-4\right)\)
=\(128-100:\left(-4\right)\)
=\(128-\left(-25\right)\)
=\(153\)
\(-141+3^3+\left(-2\right)^2\)
=\(-141+9+4\)
=\(-132+4\)
=\(-128\)
