Q.

1). 35³ + 12 - 5² = ?
2). 25³ + 14 - 12 = ?

Jawaban - ♡

• 1). 35³ + 12 - 5² = ?

= ( 35.35.35 ) + 12 - 5²

= ( 1.225.35 ) + 12 - 5²

= 42.875 + 12 - 5²

= 42.875 + 12 - ( 5 × 5 )

= 42.875 + 12 - 25

= 42.887 - 25

= 42.682

• 2). 25³ + 14 - 12 = ?

= ( 25.25.25 ) + 14 - 12

= ( 625.25 ) + 14 - 12

= 15.625 + 14 - 12

= 15.639 - 12

= 15.627

Penjelasan dengan langkah-langkah:

1)

= 35³ + 12 - 5²

= (35·35·35) + 12 - (5·5)

= 42.875 + 12 - 25

= 42.862

2)

= 25³ + 14 - 12

= (25·25·25) + 14 - 12

= 15.625 + 14 - 12

= 15.639 - 12

= 15.627
