Question

Calcule o valor das expressões

15 – { -3 + [(5 – 6)² . (9 -8 ) ² + 1]}

-2 + { -5 –[ -2 – (-2)³ - 3- (3 -2 )⁹ ] + 5 } =

Answer 1

15-{-3+[(5-6)²×(9-8)²+1]}=
15-{-3+[(1)²×(1)²+1]}=
15-{-3+[1×1+1]}=
15-{-3+[1+1]}=
15-{-3+2}=
15-{-1}=
15+1=
16

-2+{-5-[-2-(-2)³-3-(3-2)⁹]+5}=
-2+{-5-[-2-(-8)-3-(1)⁹]+5}=
-2+{-5-[-2+8-3-1]+5}=
-2+{-5-[6-3-1]+5}=
-2+{-5-[3-1]+5}=
-2+{-5-2+5}=
-2+{-7+5}=
-2+(-2)=
-2-2=
-4

BONS ESTUDOS!!!!!
