Explicație pas cu pas:

2⁶ ÷ 4² - 12² ÷ ( - 2 × 3 )² + ( - 5² )³ ÷ 5⁴

2⁶ ÷ 2⁴ - 12² ÷ ( - 2 × 3 )² × ( - 5² )³ ÷ 5⁴

2⁶ ÷ 2⁴ - 12² ÷ ( 2 × 3 )² × ( - 5² )³ ÷ 5⁴

2⁶ ÷ 2⁴ - 12² ÷ ( 2 × 3 )² - ( 5² )³ ÷ 5⁴

2² - 12⁴ ÷ ( 2 × 3 )² - ( 5² )³ ÷ 5⁴

2² - 12² / ( 2 × 3 )² - ( 5² )³ ÷ 5⁴

2² - 12² / ( ² × 3 ) ² - 5⁶ ÷ 5⁴

4 - 12² / ( 2 x 3 )² - 5⁶ ÷ 5⁴

4 - 144 / ( 2 × 3 )² - 5⁶ ÷ 5⁴

4 - 144 / 4 × 9 - 5⁶ ÷ 5⁴

4 - 144 / 4 × 9 - 5²

4 - 36 / 9 - 5²

4 - 36 / 9 - 25

4 - 4 - 25
