Question

Thực hiện phép tính: 123 + 60 : [16 - 2(5² - 20)]

 

Answer 1

\(123+60:\left[16-2\left(5^2-20\right)\right]\)

\(=123+60:\left[16-2\left(25-20\right)\right]\)

\(=123+60:\left[16-2\cdot5\right]\)

\(=123+60:6\)

\(=123+10\)

\(=133\)

Answer 2

\(123+60:\left[16-2\left(5^2-20\right)\right]\)

\(=123+60:\left[16-2\left(25-20\right)\right]\)

\(=123+60:\left(16-10\right)\)

\(=123+60:6\)

`=123+10`

`=133`

Answer 3

 

 

123+60:(16-2(2mũ5-20)

=123+60:(16-2(32-20)

=123+60:(16-2*12)

=123+60:(16-24)

=123+60:(-8)

=123+(-7,5)

=116,5

Answer 4

`= 123 + 60 : [16 - 2 xx 5]`

`= 123 + 60 : 6`

`= 133`
