Answer 1

Jawaban:

• 90³ × 10² - 900.000

• = ( 90 × 90 × 90 ) × ( 10 × 10 ) - 900.000

• = ( 8.100 × 90 ) × 100 - 900.000

• = 729.000 × 100 - 900.000

• = ( 729.000 × 100 ) - 900.000

• = 72.900.000 - 900.000

• 15² - 10 × 5

• = ( 15 × 15 ) - 10 × 5

• = 225 - ( 10 × 5 )

• = 225 - 50

Answer 2

Hallo! Saya @Nicth, akan menjawab pertanyaanmu :)

_____________________

90³ × 10² - 900.000 =

= (90 × 90 × 90) × (10 × 10) - 900.000

= 729.000 × 100 - 900.000

= 72.900.000 - 900.000

= 72.000.000

15² - 10 × 5 =

= (15 × 15) - (10 × 5)

= 225 - 50

= 175
