Answer 1

Penjelasan dengan langkah-langkah:

1.)

= 12 ÷ (-2)²

= 12 ÷ (-2 × -2)

= 12 ÷ 4

= 3

= -3² + 10

= -(3.3) + 10

= -9 + 10

= 1

= 6 - (-4)²

= 6 - (-4 × -4)

= 6 - 16

= -10

= (-6)² + (-7)²

= (-6.-6) + (-7.-7)

= 36 + 49

= 85

Answer 2

--

• Soal no 1

= 12 : (-2)²

= 12 : ( (-2) × (-2) )

= 12 : 4

= 3

• Soal no2 2

= (-3)² + 10

= ( (-3) × (-3) ) + 10

= 9 + 10

= 19

• Soal no 3

= 6 - (-4)²

= 6 - ( (-4) × (-4) )

= 6 - 16

= -10

• Soal no 4

= (-6)² + (-7)²

= ( (-6) × (-6) ) + (-7)²

= 36 + ( (-7) × (-7) )

= 36 + 49

= 85
