Question

1. Calculati : a) 1 la puterea 3 + 0 la puterea 2014 + 2014.
b) 3 la puterea 2 + 2 la puterea 3 - 2013 la puterea 1 - 1 la puterea 2014.
c) 2 la puterea 19 × 7 la puterea 19 - 14 la puterea 19
d) [( 2×3×5) -2 la puterea 8 ÷ 2 a puterea 6 ] ÷4-2 la puterea 2 × 5 la puterea 2.

Va rog. Am mare nevoie.

Answer 1

1.
a)  1³ + 0²⁰¹⁴ + 2014= 1 + 0 + 2014= 2015
b) 3² + 2³ - 2013¹ - 1²⁰¹⁴ =9 + 8 - 2013 - 1 =-1997
c) 2¹⁹× 7¹⁹ - 14¹⁹ =(2× 7)¹⁹ - 14¹⁹=14¹⁹ - 14¹⁹ =0
d) [( 2×3×5) -2⁸ ÷ 2 ⁶ ] ÷4 -2² × 5²=( 30 -4 ) ÷4-10²=26÷4-10²=6,5-100=-93,5
