Thực hiện các phép tính

120:(70-(21+(7-4)²))

Giành cho thằng nào giỏi thì làm OK !

Answer 1

120:(70-(21+(7-4)²)

= 120:(70-(21+3²)

= 120:(70-(21+9)

= 120:(70-30)

= 120:40

= 30

Answer 2

120 : ( 70 - ( 21 + ( 7-4 )² ))

= 120 : ( 70 - ( 21 + 9 ) )

= 120 : ( 70 - 30)

= 120 : 40=3

Answer 3

120:(70-(21+(7-4)^2))

=120:(70-(21+3^2))

=120:(70-(21+9))

=120:(70-30)

=120:40

=3

Answer 4

\(120:\left(70-\left(21+\left(7-4\right)^2\right)\right)\)

\(=120:\left(70-\left(21+9\right)\right)\)

\(=120:40\)

\(=3\)

Answer 5

\(120\div\left(70-\left(21+\left(7-4\right)^2\right)\right)\)

\(=120\div\left(70-\left(21+3^2\right)\right)\)

\(=120\div\left(70-30\right)\)

\(=120\div40\)

\(=30\)
