Explicație pas cu pas:

a) (4+4·3)·[(-3)⁴⁹+3·3²·3⁴⁶+(-2)¹⁴⁵:(-2)⁹⁰+(2⁵)¹¹-5²]=15·[-3⁴⁹-25+3⁴⁹+(-2)⁵⁵+2⁵⁵-25]= 15·[-25]=-375.

b) (-5)³·{396-720:[-7+(6590+51·210):(-2²·5²)]}=(-5)³·{396-720:[-7+(6590+10710):(-100)]}=(-5)³·{396-720:[-7+17300:(-100)]}=(-5)³·{396-720:[-7+(-173)]}=(-5)³·{396-720:[-180]}=(-5)³·{396+4}=-125·400=-50000

c) (|-2|)²+|7|-|(-5)²|+|(-1)¹⁶|-|-11|+4·|-5|=4+7-25+1-11+20=32-36=-4
