Answer 1

Penjelasan dengan langkah-langkah:

Lim 60x² + 100² - x

x = 2

60(2)² + 100² - 2

= 60(2²) + 100² - 2

= 60(4) + 100² - 2

= 240 + 100² - 2

= 240 + 10.000 - 2

= 10.240 - 2

= 10.238

300² - 59 + 28 - 43

= (300.300) - 59 + 28 - 43

= 90.000 - 59 + 28 - 43

= 89.941 + 28 - 43

= 89.969 - 43

= 89.926

4000 - 20 - 10 - 5

= 4000 - (20 + 10 + 5)

= 4000 - (30 + 5)

= 4000 - 35

= 3965

100² × 50 - 20 + 40

= (100.100) × 50 - 20 + 40

= 10.000 × 50 - 20 + 40

= 500.000 - 20 + 40

= 499.980 + 40

= 500.020

Answer 2

Penjelasan dengan langkah-langkah:

Lim 60x² + 100² - x

• x => 2

=> 60(2)² + 100² - 2

=> 60( 2.2 ) + ( 100.100 ) - 2

=> 60(4) + 10.000 - 2

=> 240 + 10.000 - 2

=> 10.240 - 2

=> 10.238 ✔️
