Answer 1

Olá,

3)

a)

(3,0×10⁸)×(2,0×10²) = 6,0×10⁸⁺² = 6,0×10¹⁰

b)

(4,0×10⁻⁸)×(4,0×10⁴) = 16,0×10⁻⁸⁺⁴ = 16,0×10⁻⁴ = 1,6×10⁻³

c)

(8,0×10⁶)÷(2,0×10²) = 4,0×10⁶⁻² = 4,0×10⁴

d)

(6,0×10⁻⁵)÷(2,0×10⁻⁴) = 3,0×10⁻⁵⁻⁽⁻⁴⁾ = 3,0×10⁻⁵⁺⁴ = 3,0×10⁻¹

e)

(3,0×10⁹)² = (3,0)²×(10⁹)² = 9,0×10⁹ˣ² = 9,0×10¹⁸

f)

(4,0×10⁴)³ = (4,0)³×(10⁴)³ = 64,0×10⁴ˣ³ = 64,0×10¹² = 6,4×10¹³

g)

(4,0×10⁻³)×(4,0×10⁴) = 16,0×10⁻³⁺⁴ = 16,0×10¹ = 1,6×10²

h)

(4,0×10⁻³)×(4,0×10⁻⁴) = 16,0×10⁻³⁻⁴ = 16,0×10⁻⁷ = 1,6×10⁻⁶
