Question

tính hợp lý nếu có thể

(-0,25) . 0,02 . 40 . (-50) . (-201,43)

Answer 1

\(\left(-0,25\right).0,02.40.\left(-50\right).\left(-201,43\right)\)

\(=\left(-0,25.40\right).\left(-50.0,02\right).\left(-201,43\right)\)

\(=-10.\left(-1\right).\left(-201,43\right)=-2014,3\)

Chúc bạn học tốt!!!

Answer 2

\(\left(-0,25\right).0,02.40.\left(-50\right).\left(-201,43\right)\)

\(=\left(-0,25.40\right).\left(-50.0,02\right).\left(-201,43\right)\)

\(=\left(-10\right).\left(-1\right).\left(-201,43\right)\)

\(=\left(-201,43\right)\)
