FAÇAM PASSO A PASSO TB PFVVV URGENTEEEE ​

Answer 1

Resposta:

Explicação passo-a-passo:

98.1: 2/3 - 1/2 = 4/6 - 3/6 = 1/6 → (1/6)⁷ . (1/6)³ = 1/6⁷ . 1/6³ = 1/6¹⁰

98.2: (2³)⁵ = 2¹⁵ → 2¹⁵ ÷ (1/2 - 1)¹⁵ = 2¹⁵ ÷ (1/2)¹⁵ = 2¹⁵ ÷ 1/2¹⁵ = 2¹⁵ . 2¹⁵/1 = 2³⁰

98.3: 3/8 - 1/2 = 3/8 - 4/8 = -1/8 → (-1/8)⁹ . [(-2)³]³ = (-1/8)⁹ . (-8)³ = 8³/8⁹ = 1/8⁶.

98.4: 2 . 1/3 + 1 = 2/3 + 1 = 5/3 e 2 - 1/3 = 5/3 → (5/3)⁴ . (5/3)⁷ = 5⁴/3⁴ . 5⁷/3⁷ = 5¹¹/3¹¹

* Cansei, espero que tenha ajudado
