Question

1.

-5-12

(-14).14

6-12

2.

13-18-(-42)-15

369-4{(-5)+4.(-8)}

(-8) mũ 3:(-8)mũ 2 +8

 

Answer 1

1.

-5-12=-17

(-14).14=-196

6-12=-6

2.

13-18-(-42)-15

= -5-(-42)-15

=(-5-15)-(-42)

=-20+42

=22

369-4{(-5)+4.(-8)}

= 369-4.{-5+(-32)}

=369-4.{-37}

=369-(-148)

=517

(-8)³:(-8)² +8

=-8+8

=0

Answer 2

Bài 1 :

\(\left(-5\right)-12=-17\)

\(\left(-14\right).14=-196\)

\(6-12=-6\)

Bài 2:

\(13-18-\left(-42\right)-15=22\)

\(369-4.\left[\left(-5\right)+4.\left(-8\right)\right]=517\)\

\(\left(-8\right)^3:\left(-8\right)^2+8=0\)

Study well!!

Answer 3

1

-5-12=-5+-12=-17

-14.14=-(14.14)=-196

6-12=6+-12=-6

2

13-18-(-42)-15

=-5-(-42)-15

=37-15

= 22

369-4{(-5)+.4.(-8)}

=369-4{(-5)+-32}

=369-4.-37

=369-(-148)

=517

\(\left(-8\right)^3:\left(-8^{ }\right)^2+8\)

=-512:-64+8

=8+8

=16
