Tính: [(7/2001 + 11/4002) . 2001/25 + 9/2]:[(2/193 - 3/386) . 193/17 + 33/34]
Tính hợp lý : ((2/193-3/386).193/17+33/34):((7/2001+11/4002)201/25+9/2)
Tính: [(2/193 - 3/386) . 193/17 + 33/34] : [(7/2001 + 11/4002) . 2001/25 + 9/2]
Giải cụ thể hộ mình nha
tính
\(M=\left[\left(\frac{2}{193}-\frac{3}{386}\right).\frac{193}{17}+\frac{33}{34}\right]:\left[\left(\frac{7}{2001}+\frac{11}{4002}\right).\frac{2001}{25}+\frac{9}{2}\right]\)
tính
M=\(\frac{\left[\left(\frac{2}{193}-\frac{3}{386}\right)\cdot\frac{193}{17}+\frac{33}{34}\right]}{\left[\left(\frac{7}{2001}+\frac{11}{4002}\right)\cdot\frac{2001}{25}+\frac{9}{2}\right]}\)
M=[ (\(\frac{2}{193}\)-\(\frac{3}{386}\)).\(\frac{193}{17}\)+ \(\frac{33}{34}\) ] : [ (\(\frac{7}{2001}\)+\(\frac{11}{4002}\)).\(\frac{2001}{25}\)+\(\frac{9}{2}\) ]
Tính?
1) Tính :
a) (1/2 + 0.8 - 4/3 ) . ( 107/25 + 0,3 - 1,28 )
b) [( 2/193 - 3/386 ) 193/17 + 33/34 ] : [( 7/2001 + 11/4002) . 2001/25 + 9/2 ]
c) [ 2 - ( 1/2 )1 - 4 - 1/2 ] + 1/2 - ( -2 )3/2 . 2
Giúp mk với !!
Bài 1: Tìm 2 số hữu tỉ x và y sao cho x + y = xy = x : y (y khác 0)
Bài 2: Tính:
M = [(2/193 - 3/386) . 193/17 + 33/34] : [( 7/2001 + 11/4002) . 2001/25 + 9/2]
Bài 3: Cho A = [0,8 . 7 + (0,82] . (1,25 . 7 - 4/5 . 1,25) + 31,64
B \(\left(1,09-0,29\right).\frac{5}{4}\)trên \(\left(18,9-16,65\right).\frac{8}{9}\)
Hỏi A gấp mấy lần B?
M = [(\(\frac{3}{4}\)+ \(\frac{3}{386}\))] . \(\frac{193}{17}\). \(\frac{33}{34}\)] : [(\(\frac{7}{2011}\)+ \(\frac{11}{4002}\)) . \(\frac{2001}{25}+\frac{9}{2}\)]
E = [193/-17 ( 2/193 - 3/386 ) + 11/34] : [(7/1931 + 11/3862) 1931/25 +9/2]
