Am nevoie de ex 8!!!!!Dau coroana!!!

Answer 1

Răspuns:

a){[5×(-1)]¹⁰:5⁸-6²}×2⁴-9=[(-5)¹⁰:5⁸-6²]×2⁴-9=

=(5²-6²)×2⁴-9=(25-36)×2⁴-9=(-9)×16-9=-144-9=-123

b){1-[9-25+32]:1×1+9}:(-8)=[1-16:1+9]:(-8)=(-15+9):(-8)=

=(-24)÷(-8)=3

c)[8³⁶:2¹⁰⁶+9⁵⁴:3¹⁰⁶+5⁴⁸:25²³]:2×3=

=[(2³)³⁶:2¹⁰⁶+(3²)⁵⁴:3¹⁰⁶+5⁴⁸:(5²)²³]:2×3=

=[2¹⁰⁸:2¹⁰⁶+3¹⁰⁸:3¹⁰⁶+5⁴⁸:5⁴⁶]:2×3=(2²+3²+5²):2×3=

(4+9+25):2×3=38:2×3=19×3=57
