Answer 1

Jawaban:

1. 1.385

2. 125

3. 512

4. 64

Penjelasan dengan langkah-langkah:

1. 12³ - 7³

= (12 × 12 × 12) - (7 × 7 × 7)

= (144 × 12) - (49 × 7)

= 1.728 - 343

= 1.385

2. (12 - 7) ³

= 12 - 7 = 5

= 5³

= 5 × 5 × 5

= 25 × 5

= 125

3. 4³ × 2³

= (4 × 4 × 4) × (2 × 2 × 2)

= (16 × 4) × (4 × 2)

= 64 × 8

= 512

4. 8³ ÷ 2³

= (8 × 8 × 8) ÷ (2 × 2 × 2)

= (64 × 8) ÷ 8

= 512 ÷ 8

= 64

Answer 2

12³ - 7³

= ( 12 × 12 × 12 ) - ( 7 × 7 × 7 )

= ( 144 × 12 ) - (49 × 7 )

= 1.728 - 343

= 1.385

( 12 - 7 )³ <= tanda kurung harus dikerjakan terlebih dahulu

= ( 12 - 7 )³

= 5³

= 5 × 5 × 5

= 25 × 5

= 125

4³ × 2³

= ( 4 × 4 × 4 ) × ( 2 × 2 × 2 )

= ( 16 × 4 ) × ( 4 × 2 )

= 64 × 8

= 512

8³ ÷ 2³

= ( 8 × 8 × 8 ) ÷ ( 2 × 2 × 2 )

= ( 64 × 8 ) ÷ ( 4 × 2 )

= 512 ÷ 8

= 64
