Question

Faça as operações a) 2,5x10^-12x10^35 b)6,38x10^-6/2x10^-8 c)3,98x10^5+9,51x10^6 d)2,51x10,^3-1,11x10^4 me ajudem help!!!!!​

Answer 1

2,5 ₓ 10⁻¹² ₓ 10³⁵

2,5 ₓ 10⁻¹²⁺³⁵

2,5 ₓ 10²³

6,38 ₓ 10 ⁻⁶/2 ₓ 10⁻⁸

(6,38 ₓ 10⁻⁶⁺⁸)/2

3,19 ₓ 10²

3,98 ₓ 10⁵ + 9,51 ₓ 10⁶

(3,98 + 9,51) ₓ 10 ⁵⁺⁶

13,49 ₓ 10¹¹

1,349 ₓ 10¹²

2,51 ₓ 10³ ₓ 1,11 ₓ 10⁴

(2,51 ₓ 1,11) ₓ 10 ³⁺⁴

2,7861 ₓ 10⁷
