Explicație pas cu pas:
a) a= 6×(-30+24)= 6×(-6)= -36
b= 6×(28-26)= 6×2=12
n= 2a-b= 2×(-36)-12= -72-12= -84
b) 16×[ 9- (-56)÷(-8)-6] = 16×(9-7-6)= 16×(-4) = -64
c) 6×(56-54-5)= 6×(-3)= -18
d) (-54 + 8×7)² - 216÷(8×9) +(-64+9×7)²-(3⁶)÷(-3)⁵=
(-54+56)² - 216÷72+(-64+63)²-3=
2²- 3+ (-1)²-3= 4-3+1-3= -1
e) -36÷12 +(-8×3+25)¹³-64÷(-2⁶) -(-50+16×3)² =
-3+(-24+25)¹³-1 -(-50+48)²= -3+1-1-(-2)²= -3+4= 1
