f) ( 3,2x10-3) : (4x10-16)

Answer 1

Resposta:

d) 0.5 × 10¹¹ ÷ 22.4 × 10⁸

⠀⠀(0.5 ÷ 22.4) × 10¹¹⁺⁸

⠀⠀0.022 × 10¹⁹

⠀⠀2.2 × 10¹⁷

e) 802 × 10¹² ÷ 52 × 10¹³

⠀⠀(802 ÷ 52) × 10¹²⁺¹³

⠀⠀15.42 × 10²⁵

⠀⠀1.542 × 10²⁶

f) (3.2 × 10⁻³) ÷ (4 × 10⁻¹⁶)

⠀⠀(3.2 ÷ 4) × 10⁻³⁻⁽⁻¹⁶⁾

⠀⠀0.8 × 10⁻³⁺¹⁶

⠀⠀0.8 × 10¹³

⠀⠀8 × 10¹²
