Question

Помогите Пожалуйста((((

Answer 1

3² * 3⁴⁻⁸ˣ = 3⁶⁻³ˣ
3⁶⁻⁸ˣ = 3⁶⁻³ˣ
6 - 8х = 6 - 3х
5х = 0
х = 0
2)2ˣ(2⁴ -1) = 120
    2ˣ * 15 = 120
2ˣ = 8
х = 3
3) 5ˣ⁻¹(10 + 5²) = 7
    5ˣ⁻¹ * 35 = 7
   5ˣ⁻¹ *5 = 1
   5ˣ = 1
    х = 0
4) 7ˣ - 7ˣ⁻¹ = 6
7ˣ⁻¹(7 -1) = 6
7ˣ⁻¹ = 1
х -1 = 0
х = 1
5) 3ˣ(4*3² + 5*3 -6) = 5
     3ˣ*45 = 5
     3ˣ *9 = 1
     3ˣ⁺² = 1
х +2 = 0
х = -2
