123+0
11+33
a) -123.(2021-90) +2021.123 b) -123. ( 45- 33) + 33. ( 45-123 )
123+123
22+33=
123/56*3-12+65/12*22+11-22*22/33/5*123=? khó lắm
Tính:
a) (123 - 37) - 123; b) (-224) - (34 - 224);
c) 126 - (126- 33) d) (-53 - 23) - (567 - 53)
a) (123 - 37) -123 -123 - 37 -123 = (123 -123) - 37 = -37.
b) (-224) - (34 - 224) = -224 - 34 + 224 - (-224 + 224) - 34 = -34.
c) 126 - (126 - 33) = 126 -126 + 33 = 33.
d) (-53 - 23) - (567 - 53) - -53 - 23 - 567 + 53 = -590
a) (123 - 37) -123 -123 - 37 -123 = (123 -123) - 37 = -37.
b) (-224) - (34 - 224) = -224 - 34 + 224 - (-224 + 224) - 34 = -34.
c) 126 - (126 - 33) = 126 -126 + 33 = 33.
d) (-53 - 23) - (567 - 53) - -53 - 23 - 567 + 53 = -590
33/785-123/751+759/158=????????????????????????????????????????????????????????????????????????????
f) F = [(123 – 17) – (123 + 33)] – {34 – [34 + (57 – 50) – 7]}
Các bạn giúp mình gấp
THANK YOU
Ta có
F=[(123-17)-(123+33)]- {34-[34+(57-50)-7]}
F=(123-17-123-33)-(34-34+7-7)
F=(0-50)-0+=O
F=-50+
Tìm x (2x-123):3=33 giúp mình với
\(\dfrac{2x-123}{3}=33\)
<=> \(2x-123=99\)
<=> \(2x=222\)
<=> x = 111
\(\Leftrightarrow2x-123=99\)
hay x=111
63-[(12-123)3:4].27
(-33)+(-66)
giúp mình với.
a: \(=63-\left[\left(-111\right)^3:4\right]\cdot27=9231572,25\)
b: =-(33+66)=-99
11+22+( X x 2 + X x 199) : 33 = 123 x123
11 + 22 + ( \(x\) x 2 + \(x\) x 199 ) : 33 = 123 x 123
33 + \(x\) ( 2 + 199) : 33 = 15129
201\(x\) : 33 = 15129 - 33
201\(x\) : 33 = 15096
201\(x\) = 15096 x 33
201\(x\) = 498168
\(x\) = 498168 : 201
\(x\) = 166056/67
