Answer 1

\(A=137.454+206\)

\(A=137.\left(453+1\right)+206\)

\(A=137.453+137.1+206\)

\(A=137.453+343\)

\(V\text{à}\)

\(B=453.138-110\)

\(B=453.\left(137+1\right)-110\)

\(B=453.137+453.137-110\)

\(B=453.137+343\)

\(137.453+343=453.137+343\)

\(\Rightarrow A=B\)

Answer 2

Answer 3

Bài Làm

A=137.454+206

A=137.(453+1)+206

A=137.453+137.1+206

A=137.453+343

Và

B=453.138−110

B=453.(137+1)−110

B=453.137+453.137−110

B=453.137+343

137.453+343=453.137+343

⇒A=B

Answer 4

A=137x454+206

A=62,198+206

B=62,514-110

B=62,404

=>A=B=62,404

Answer 5

A=137x454+206

A=62,198+206

A=62,404

B=453x138-110

B=62,514-110

B=62,404

=>A=B=62,404
