146.25: 2.25
2.25 x 0.5 + 2.25 : 2 + 3.75
=2.25*\(\left(0.5+2\right)\)+3.75
=2.25*2.5+3.75
=5.625+3.75
=5.7

anh đỗ thanh hải ơi giúp em bài toán ở dưới với huhu
8^2.25^3 = ?
2.25-x+0.9=0.57
2.25-x+0.9=0.57
2,25 -x + 0,9 =0,57
2,25 -x =0,57-0,9
2,25 -x =-0.33
x= 2,25- 0,33
x= 2,58
2,25 - x + 0,9 = 0,57
x + 0,9 = 2,25 - 0,57
x + 0,9 = 1,5
x = 1,5 - 0,9
x = 0,6
2,25 - x + 0,9 = 0,57.
2,25 - x = 0,57 - 0,9.
2,25 - x = -0,33.
x = 2,25 - -0,33.
x = 2,58.
Tk mk nha!!!
Thank you very much!!!
2.1+2.2+2.3+2.4+......+2.25
12,5+x:0.25-2.25=12.25
12,5+x:0,25-2,25=12,25
x:0,25=12,25+2,25-12,5
x:0,25=2
x =2x0,25
x = 0,5
12,5+x:0.25-2.25=12.25
x : 0,25 = 12,25 + 2,25 - 12,5
x : 0,25 = 2
x = 2 x 0,25
x = 0,5
180:{300:[450-(4.5^3-2^2.25)]}
