Question

So sánh A và B biết :

A = 19,19 x 2525, 25                   B = 25, 25 x 1919,19

Answer 1

A = 19,19 x 2525,25

A = 19 x 1,01 x 25 x 101,01

B = 25,25 x 1919,19 

B = 25 x 1,01 x 19 x 101,01

Vậy A = B 

Answer 2

\(\text{+)}\)

\(A=19,19.2525,25\)
\(A=19.1,01.25.101,01\)

\(\text{+)}\)

\(B=25,25.1919,19\)

\(B=25.1,01.19.101,01\)

\(\Rightarrow A=B\)
