Question

tính hợp lí : 124.52+124+(-124).(-47) , giúp mk

Answer 1

124 . 52 + 124 + ( - 124 ) . ( - 47 )

= 124 . 52 + 124 + 124 . 47

= 124 . ( 52 + 1 + 47 )

= 124 . 100

= 12 400

Answer 2

\(124\times52+124+\left(-124\right)\times\left(-47\right)\)

\(=124\times52+124+124\times47\)

\(=124\times\left(52+1+47\right)\)

\(=124\times100\)

\(=12400\)
