Answer 1

Respuesta:

1. 21 × 4 = 84

2. 10 × 10 × 10 × 10 = 10000 (Cuándo multipliques por 10, solo fíjate en los ceros digamos 10 × 10 = 100, son dos ceros que se le agrega al 1. )

3. 4 × 4 × 4 × 5 × 5 × 5 = 64 × 125 = 8000

4. (3 × 3 × 3) (3 × 3 × 3 × 3) = 27 × 81 = 2187

5. (7 - 7 - 7) + (7 - 7) = -7 + 0 = -7
