Answer 1

Step-by-step explanation:

26) 3²ˣ⁺¹= 1

=> 3²ˣ⁺¹= 3⁰ (common base hence exponents ate equal )

=> 2x+1 = 0

=> x = -1/2

30) 9*3ˣ = (27)²ˣ⁻⁵

=> 3²*3ˣ = 3³⁽²ˣ⁻⁵⁾

=> 3²⁺ˣ = 3⁶ˣ⁻¹⁵

=> 2+x = 6x - 15

=> 2+15=6x-x

=> 17 = 5x

=> x = 17/5

32) 5ˣ⁻³ * 3²ˣ⁻⁸ = 225

=> 5ˣ⁻³ * 3²ˣ⁻⁸ = 5² * 3²

=> on comparing like terms, we get

=> 5ˣ⁻³ = 5²

=> x-3 = 2 => x = 5 --------1

=> 3²ˣ⁻⁸ = 3²

=> 2x-8 = 2 => 2x = 10 => x = 5--------2
