c){6-[282×(-1)-(45:11-18)]}-644=
d)25²:(-5)²- {42+3×[6-(3³×5+11)] }=​

Answer 1

Explicație pas cu pas:

a) 144:(-12)+7x(-2)³+2010=

-12+7x(-8)+2010=

-12+(-56)+2010=

-68+2010=1942

b) -88:(-4)-125:(-5)²-389=

22-5-389= -372

c) nu l am facut ca m a indus in eroare 45:11

d) 25²:(-5)²-{42+3x[6-(3³x5+11)]}=

125:25-{42+3-[6-(27x5+11)]}=

5-{42+3-[6-(135+11)]}=

5-(42+3-(-140)=

5-185= -180
