Question

Thực hiện phép tính

80-[130-(12-4)^2]

Answer 1

\(\text{80-[130-(12-4)^2]}=14\)

Answer 2

\(80-\left[130-\left(12-4\right)^2\right]=80-\left[130-8^2\right]=80-\left[130-64\right]=80-66=14\)

Answer 3

\(80-\left[130-\left(12-4\right)^2\right]\)

\(=80-\left[130-8^2\right]\)

\(=80-\left[130-64\right]\)

\(=80-66\)

\(=14\)

Answer 4

\(80-\left[130-\left(12-4\right)^2\right]\)

\(=80-\left[130-8^2\right]\)

=\(80-\left[130-64\right]\)

=\(80-66=14\)
