a) 3+ [4 +(5-4) -2] ³ =
= 3+(4+1-2)³=
=3+(5-2)³=
=3+(3) ³=
=3+27=
=30
b) 1+2 ×3³ + 3 × (2-1)⁴=
= 1+2 × 27 + 3 × 1⁴=
= 1+54+3 ×1=
= 1+54+3=
=55+3=
=58
c) 5+{[(2 × 3²-4²)× 2+2³]:6-1}²=
=5+{[(2 ×9+16)×2+8]:6-1}²=
=5+{[(18+16)×2+8]:6-1}²=
=5+[(34×2+8):6-1]²=
=5+[(68+8):6-1]²=
=5+(76:6-1)²=
=5+(12-1)²=
=5+11²=
=5+121=
=126 (la ultimul punct nu mi-a iesit impartirea asa ca am aproximat.)
