gente me ajuda a fazer isso, a partir do 3 pfvr

Answer 1

a) 2ˣ = 1/32
   
    2ˣ = 2⁻ ⁵ → x = - 5

b) 11²ˣ ⁻ ⁷ = 11

     2x - 7 = 1

     2x = 1 +7
    
    2x = 8→ x = 4

c)7ˣ ⁻ ³ = 1

7ˣ ⁻ ³ = 7⁰

x - 3 = 0

x = 3

d) 9ˣ⁺³ = 81

9ˣ⁺³ = 9²

x + 3 = 2

x = 2 - 3

x = - 1

e) 2ˣ⁺⁶ = 1/16

2ˣ⁺⁶ = 2 ⁻⁴

x + 6 = - 4

x = - 4 - 6

x = - 10
