Qᴜɪᴢ 1. (4² × 10²) + 120 = 2. 640 – (6² + 12²) =

1. (4² × 10²) + 120

= ((4×4) × (10×10)) + 120

= (16× 100) + 120

= 1.600 + 120

= 1.720

2. 640 – (6² + 12²)

= 640 – ((6×6) + (12×12))

= 640 – (36+144)

= 640 – 180

= 460

Jawaban:

1. 1.720

2. 460

Penjelasan dengan langkah-langkah:

1. (4²×10²)+120=

(16×100)+120=

1.600+120=1.720

2. 640-(6²+12²)=

640-(36+144)=

640-180=460
