Question

thực hiện phép tính: 100 - [120 - (15 - 5)^2]

Answer 1

\(100-\left[120-\left(15-5\right)^2\right]=100-\left(120-10^2\right)\)

\(=100-120+100=200-120=80\)

Chúc bạn học tốt!!!

Answer 2

\(100-\left[120-\left(15-5\right)^2\right]\)

\(=100-\left[120-10^2\right]\)

\(=100-\left[120-100\right]\)

\(=100-20\)

= \(80\)

Answer 3

= 100 - ^{\(\left[120-100\right]\)}

= 100 - 20

= 80
