Question

rút gọn :  \(A=\frac{4116-14}{10290-35}\)​​

 

Answer 1

A=\(\frac{14.294-14}{35.294-35}=\frac{14.\left(294-1\right)}{35.\left(294-1\right)}=\frac{14}{35}=\frac{2}{5}\)

Answer 2

ƯCLN(4116,35)=7

ƯCLN(14,10290)=14

Nên rút gọn thành: 588-1/735-5

Answer 3

\(\frac{4116-14}{10290-35}=\frac{2}{5}\)

Answer 4

=>\(A=\frac{2^2.3.7^3-2.7}{2.3.5.7^3-3.7}\)=\(\frac{2-2}{5-3}\)=0

Answer 5

A = \(\frac{14.294-14}{35.294-35}\)= \(\frac{14.\left(294-1\right)}{35.\left(294-1\right)}\)= \(\frac{14}{35}\)= \(\frac{2}{5}\)
