Ai làm nhanh mik tick nha 

Answer 1

e, \(\left(-9\right).\left(-3\right):\left(-27\right)\)

\(=27:\left(-27\right)\)

\(=-1\)

f, \(26-\left(-4\right)+7-20\)

\(=30+7-20\)

\(=37-20\)

\(=17\)

g, \(235+\left(-486\right)+\left(-135\right)+376\)

\(=-251+\left(-135\right)+376\)

\(=\left(-386\right)+376\)

\(=-10\)

h, \(125+\left[17+20+\left(-125\right)\right]\)

\(=125+\left[37+\left(-125\right)\right]\)

\(=125+\left(-88\right)\)

\(=37\)
