Tính giá trị của các biểu thức:
a) \(-5,13:\left(5\frac{5}{28}-1\frac{8}{9}.1,25+1\frac{16}{63}\right)\)
b) \(\left(3\frac{1}{3}.1,9+19,5:4\frac{1}{3}\right).\left(\frac{62}{75}-\frac{4}{25}\right)\)
GIẢI ĐẦY ĐỦ BÀI NÀY GIÚP MK VS MK CẦN RẤT GẤP!
tính giá trị biểu thức :
a) \(A=-5,13:\left(5\frac{5}{28}-1\frac{8}{9}.1,25+1\frac{16}{63}\right)\)
b) \(B=\left(3\frac{1}{3}.1,9+19,5:4\frac{1}{3}\right).\left(\frac{62}{75}-\frac{4}{25}\right)\)
Tinh:
A=-5,13:\(\left(5\frac{5}{28}-1\frac{8}{9}.1,25+1\frac{16}{63}\right)\)
B=\(\left(3\frac{1}{3}.1,9+19,5:4\frac{1}{3}\right)\).\(\left(\frac{62}{75}-\frac{4}{25}\right)\)
tính giá trị của các biểu thức sau
A = - 5,13 : \(\left(5\frac{5}{28}-1\frac{8}{9}\times1,25+1\frac{16}{63}\right)\)
B = \(\left(3\frac{1}{3}\times1,9+19,5:4\frac{1}{3}\right)\times\left(\frac{62}{75}-\frac{4}{25}\right)\)
Bài 1 Tìm x
a) 3,2.x +(1,2).x+2,7= -4,9
b) (-5,6).x+2,9.x-3,86= -9,8
Bài 2
A = \(-5,13:\left(\frac{145}{28}-\frac{17}{9}.1,25+1\frac{16}{63}\right)\)
B= \(\left(3\frac{1}{3}.1,9+19,5:4\frac{1}{3}\right).\left(\frac{62}{75}-\frac{4}{25}\right)\)
giuk mik tickcho nhé
Bài 1: Tính giá trị biểu thức:
A = \(-1,53:\left(5\frac{5}{28}-1\frac{8}{9}.1,25+1\frac{16}{83}\right)\)
B = \(\left(3\frac{1}{3}.1,9+9,5:4\frac{1}{3}\right):\left(\frac{62}{75}-\frac{4}{25}\right)\)
\(\frac{0.5=0,\left(3\right)-0,1\left(6\right)}{2,5+1,6-0,8\left(3\right)}\)
\(-1,53:\left(5\frac{5}{28}-1\frac{8}{9}.1,25+1\frac{16}{63}\right)\)
\(\left(3\frac{1}{3}.1,9+9,5:4\frac{1}{3}\right).\left(\frac{62}{75}-\frac{4}{25}\right)\)
\(\frac{\left(81,624:4,8-4,505\right)^2+125.0,75}{\left\{\left[\left(0,44\right)^2:0,88+3,53\right]^2-\left(2,75\right)^2\right\}:0,52}\)
\(\frac{6^6+6^3.3^3+3^6}{_{-73}}\)
\(\frac{8^{20}+4^{20}}{4^{25}+64^5}\)
\(\frac{45^{10}.5^{20}}{75^{15}}\)
\(16\frac{3}{5}.-\frac{1}{3}-13\frac{3}{5}.\frac{-1}{3}+\frac{3}{4}\)
\(\left(1\frac{1}{2}-0,5\right):9-30^2+\frac{1}{3}-\frac{1}{6}\)
Làm nhanh giúp mk nha!!!!!!!!!!!!!!
Tính giá trị biểu thức:
A= -5,13 : [5\(\frac{5}{28}\)- 1\(\frac{8}{9}\)* 1,25 +1\(\frac{16}{63}\)]
B= [3\(\frac{1}{3}\)* 1,9 + 19,5 : 4\(\frac{1}{3}\)] * [\(\frac{62}{72}\)-\(\frac{4}{25}\)]
A = \(\left(-1+3\frac{2}{5}+\frac{1}{4}\right):\left(-4\right)\)
B = \(\left(0,645:0,3-1\frac{17}{150}\right):\left(4:6,25-\frac{1}{5}+\frac{1}{7}.1,96\right)-11,125\)
C=\(11,26-5,13:[5\frac{5}{28}-1\frac{8}{9}.1,25+1\frac{16}{63}]\)
