Question

tinh về cách thuận tiện nhất 35,7 *101 - 3,57 =?

Answer 1

35,7 *101 - 3,57

= 35,7 *101 - 3,57*1

= 35,7*(101-1)

= 35,7*100

= 3570

Answer 2

\(35,7.101-3,57\)

\(=3,57.10,1-3,57\)

\(=3,57.\left(10,1-1\right)\)

\(=3,57.9,1\)

\(=32,487\)

Answer 3

\(35,7\times10,1-3,57\)

\(=35,7\times10,1-3,57\times1\)

\(\)\(=35,7\times\left(101-1\right)\)

\(=35,7\times100\)

\(=3570\)
