Tính bằng cách thuận tiện nhất :
-23.63+23.21-58.23
\(\left(-23\right).63+23.21-58.23\)
\(=23.\left(-63+21-58\right)\)
\(=23.\left(-100\right)\)
\(=-2300\)
Có: -23.63+23.21-58.23
= 23. -63 + 23 . 21 - 58 . 23
= 23 ( -63 + 21 - 23 )
= 23 . -65
= -1495
\(-23.63+23.21-58.23=23.\left(-63\right)+23.21-23.58\)
\(=23.\left[\left(-63\right)+21-58\right]=23.\left(-100\right)=\left(-2300\right)\)
Tính hợp lý(nếu có thể)
-23.63+23.21-58.23
-23.63 + 23.21 - 58.23
= 23.-63 + 23.21 + 23.-58
= 23.(-63+21+-58)
=23.-100
=-2300
\(-23.63+23.21-58.23\\ =23.\left(-63\right)+23.21-58.23\\ =23\left(-63+21-58\right)\\ =23.\left(-100\right)=-2300\)
-23 . 63 + 23 . 21 - 58 . 23
= 23 . (-63 + 21 - 58) = 23 . (-100) = -2300
Tính hợp lí:
-23.63+23.21-58.23
Giúp mk nha!!
^-^
-23.63+23.21-58.23
= 23. (-63) + 23.21 - 58.23
= 23.( -63 + 21-58)
= 23. (-100)
= -2300
-23.63+23.21-58.23=23.-63+23.21-58.23=23(-63+21-58)=23.-100=-2300
\(-23.63+23.21-58.23\)
\(=-63.23+21.23-58.23\)
\(=23.\left(21-58-63\right)\)
