Срочно помогите плиз!!! 1) (-128):(-4):(-8):22) -72*18+36*16+36*(-4)3)(-3^3):(-3^2)+(-2^3):(-1^4)-(-1^8):(-1^7)​

Answer 1

Ответ:

А что это за знаки в третьем? Если объясните что это значит, то я и третий пример решу

Answer 2

Ответ:1) =-128:(-4)=32=-8:2=-4=32:(-4)=-8

2) =36•(-4)=-144=-72•18=-1296=36•16=576=-1296+576=-720=-720+(-144)=864

3) = -3^3:(-3^2)=3=-2^3:(-1^4)=8=-1^4:(-1^7)=1=3+8-1=10

Answer 3

Calculation:

Let's solve the given expressions step by step:

1) (-128):(-4):(-8):22

To solve this expression, we need to perform the division operation from left to right:

-128 ÷ -4 = 32 32 ÷ -8 = -4 -4 ÷ 22 = -0.18181818181818182

Therefore, the value of the expression (-128):(-4):(-8):22 is approximately -0.1818.

2) -72*18+36*16+36*(-4)

To solve this expression, we need to perform the multiplication and addition operations:

-72 * 18 = -1296 36 * 16 = 576 36 * (-4) = -144

Now, let's add the results:

-1296 + 576 + (-144) = -864

Therefore, the value of the expression -72*18+36*16+36*(-4) is -864.

3) (-3^3):(-3^2)+(-2^3):(-1^4)-(-1^8):(-1^7)

To solve this expression, we need to evaluate the exponentiation and division operations:

-3^3 = -27 -3^2 = -9 -2^3 = -8 -1^4 = 1 -1^8 = 1 -1^7 = -1

Now, let's perform the divisions:

-27 ÷ -9 = 3 -8 ÷ 1 = -8 1 ÷ -1 = -1

Finally, let's add the results:

3 + (-8) + (-1) = -6

Therefore, the value of the expression (-3^3):(-3^2)+(-2^3):(-1^4)-(-1^8):(-1^7) is -6.
