Question

Sa se efectueze: a) 2 la puterea a 3 + 2 la puterea a 2 + 2 la puterea 2000 x (3 la puterea a 2 - 2 la puterea a 3 - 5 la puterea 0)
b) (5 x 23-2 la puterea a 2) : 2 la puterea a 3 +672:16

Answer 1

a) 2³+ 2²+ 2²⁰⁰⁰ x (3² - 2³ - 5⁰)= 2²*(2+1)+ 2²⁰⁰⁰ x (9 - 8 1)=2²*3+2²⁰⁰⁰ *0=
=4*3+0=12


b) (5 x 23-2²) : 2³ +672:16=(115-4) : 8+42=111: 8+42=13,875+42=55,875
