urgent dau coroana si multe puncte pls

Answer 1

[–3+(–6–4+5):(+3+7–9)]:(–4) = 2

[-3+(-10+5):(10-9)] : (-4)

[-3+(-5):(+1)] : (-4)

(-3-5):(-4)

(-8) : (-4) = 2

[+8–(–9+2+5):(–8+3+4)]:(–2) =

[8-(-7+5) : (-5+4) ] : (-2)

[8-(-2) : (-1)] : (-2)

(8-2) : (-2)

6 : (-2)

-3

[+7–(–9+7+4):(–5+4–1)]:(–2) = -4

[ 7-(-2+4) : (-1-1)] : (-2)

[7-(+2) :(-2) ] : (-2)

[7-(-1) ] : (-2)

8 : (-2)

-4

[+1–(+4–6–7):(–8+2+3)]:(–2) = 1

[1-(-2-7) : (-6+3)] : (-2)

[1-(-9) : (-3)] : (-2)

(1-3) : (-2)

(-2) : (-2)

Răspuns:

Explicație pas cu pas:

$\large \bf [ - 3 + ( - 6 - 4 + 5) : ( + 3 + 7 - 9)] : ( - 4) =$

$\large \bf [ - 3 + ( - 5) : ( +1)] : ( - 4) =$

$\large \bf ( - 3 - 5) : ( - 4) =$

$\large \bf ( - 8) : ( - 4) =$

$\color{red}\Large \boxed{\bf 2}$

                                                       

$\large \bf [ + 8 - ( - 9 + 2 + 5) : ( - 8 + 3 + 4)] : ( - 2) =$

$\large \bf [ + 8 - ( - 2) : ( - 1)] : ( - 2) =$

$\large \bf [ + 8+2 : ( - 1)] : ( - 2) =$

$\large \bf ( + 8-2 ) : ( - 2) =$

$\large \bf ( + 6 ) : ( - 2) =$

$\color{blue}\Large \boxed{\bf -3}$

                                                       

$\large \bf [ + 7 - ( - 9 + 7 + 4) : ( - 5 + 4 - 1)] : ( - 2) =$

$\large \bf [ + 7 - 2 : ( - 2)] : ( - 2) =$

$\large \bf (+ 7 +1) : ( - 2) =$

$\large \bf 8 : ( - 2) =$

$\color{indigo}\Large \boxed{\bf -4}$

                                                       

$\large\bf [ + 1 - ( + 4 - 6 - 7) : ( - 8 + 2 + 3)] : ( - 2) =$

$\large\bf [ + 1 - ( -9) : ( - 3)] : ( - 2) =$

$\large\bf [ + 1 +9 : ( - 3)] : ( - 2) =$

$\large\bf ( + 1 -3) : ( - 2) =$

$\large\bf ( -2) : ( - 2) =$

$\color{orangered}\Large \boxed{\bf 1}$
