Question

b 125: (-5)2 + (-1).(-24): (-23) - 144:32 =
C [24.(-3): 62 - 48 :(-32)] :(-19) =
d (-32:(-42) +42:(-7)] : 22 + 273: (-9)4 =​

Answer 1

Răspuns:

b) 125: (-5)² + (-1)⁴×(-24): (-2³) - 144:3² =

5³:(-5)²+1×(-24):(-8)-144:9=

5+(-24):(-8)-16=

5+3-16=

8-16= -8

c) [2⁴×(-3)⁴: 6² - 48 :(-3×2³)] :(-19) =

[16×81:36-48:(-3×8)]:(-19)=

[1296:36-48:(-24)]:(-19)=

[36-(-2)]:(-19)=

38:(-19)=2

d) [-32:(-4²) +42:(-7)] : 2²+ 27³: (-9)⁴=

[-32:16+(-6)]:4+3⁹:3⁸=

[-2+(-6)]:4+3=

(-8):4+3=

-2+3=1
