Care stie sa rezolve:
6+2x[(3x5 la puterea 2 -4x18:3 la puterea a 2 + 3x11);2 la p. 4]

Answer 1

6 + 2 × [(3 × 5^2 - 4 × 18:3^2 + 3×11) : 2^4] =

6 + 2 × [(3 × 25 - 4 × 18 : 9 + 33) : 16 ] =

6 + 2 × [ (75 - 4 × 2 + 33) : 16 ] =

6 + 2 × [(75 - 8 + 33) : 16 ] =

6 + 2 × (100 : 16) =

6 + 2 × 100/16 =

6 + 100/8 =

6 + 12,5 =

18,5
