Question

Đây là bài cuối hơi khó ạ🥺

Answer 1

( 125 x 0,75 + 125 x 25% ) x ( 9 x 11 - 0,9 x100 - 0,9 x10)

=( 125 x 0,75 + 125 x 25% ) x          0

=          0

Answer 2

(125*0,75+125*25%)*(9*11-0,9*100-0,9*10)

=125*(0,75+0,25)*9(11-10-1)

=125*1*9*0=0

Answer 3

`(125xx0,75+125xx25%)xx(9xx11-0,9xx100-0,9xx10)`

`=(125xx0,75+125xx0,25)xx(9xx11-9xx10-9xx1)`

`=(125xx(0,75+0,25))xx(9xx(11-10-1))`

`=(125xx1)xx(9xx0)`

`=125xx0`

`=0`

Answer 4

\(\left(125\times0,75+125\times25\%\right)\times\left(9\times11-0,9\times100-0,9\times10\right)\)

\(=\text{​​}\left(125\times0,75+125\times0,25\right)\times\left(99-90-9\right)\)

\(=\text{[125(0,75+0,25)]}\times0\)

\(=\left(125\times1\right)\times0\)

\(=125\times0\)

\(=0\)

Answer 5

=0
