\(M=\frac{\left(53+1\right)x107-53}{53x107+54}\)
\(M=\frac{53x107+107-53}{53x107+54}\)
\(M=\frac{53x107+54}{53x107+54}\)
\(M=1.\)
Tính giá trị biểu thức sau theo cách hợp lí nhất:
\(\frac{54x107-53}{53x107-54}\)
so sanh : a= 54x107-53 / 53x107+54 ; b= 135x269-133 / 134x269+135
So sánh A và B : A= \(\dfrac{54x107-53}{53x107+54}\)B=\(\dfrac{135x269-133}{134x269+135}\)
\(\frac{1}{3x7}+\frac{1}{7x11}+.....+\frac{1}{Xx\left(Xx4\right)}=\frac{5}{63}\)
Ai nhanh mk tik nha!
Tính nhanh:
\(\left(30:7\frac{1}{2}+0,5\times31,5\right)\times\left(4\frac{1}{2}-\frac{9}{2}\right):\left(1,45\times10\right)\)
Ai nhanh mk tik cho 3 tik nha ^_^
\(\frac{1}{3}+\frac{5}{6}:\left(X-2\frac{1}{5}\right)=\frac{3}{4}\)
Các bn giúp mk phép tìm X này nha!Ai nhanh mk cho 3 tik
\(C=\frac{2}{3}+\frac{2}{15}+\frac{2}{35}+\frac{2}{63}+\frac{2}{99}+\frac{2}{143}\) Ai nhanh mk tik nha!!!!💎💎
\(\frac{45}{20}+\frac{25}{20}=???\)
ai nhanh mk tik cho nha
\(A=\frac{5}{11x16}+\frac{5}{16x21}+\frac{5}{21x26}+....+\frac{5}{61x66}\)
