adalah

tolong ​

Answer 1

Penjelasan dengan langkah-langkah:

= (-2)² + (-2)² - (-2)¹ + (-2)^-1

= [(-2)x(-2)] + [(-2)x(-2)] - [(-2)] + [1/(-2)]

= [4] + [4] + [2] - [1/2]

= 10 - 1/2

= [20 - 1]/2

= 19/2

= 9 ½

Answer 2

1.) (-2)² + (-2)² - (-2)¹ + (-2)-¹

= (-2 × (-2)) + (-2)² - (-2)¹ + (-2)-¹

= 4 + (-2)² - (-2)¹ + (-2)-¹

= 4 + (-2 × (-2)) - (-2)¹ + (-2)-¹

= 4 + 4 - (-2)¹ + (-2)-¹

= ( 4 + 4 ) - (-2)¹ + (-2)-¹

= 8 - (-2)¹ + (-2)-¹

= 10 - 1/2

= 10/1 - 1/2

= ( 10 × 2 ) - ( 1 × 1 )/1 × 2

= 20 - 1/2

= ( 20 - 1 )/2

= 19/2

= 9 1/2
