Question

determine the value of x in (2/3)3 × (2/3)-6=(2/3)2x-1

Answer 1

Answer:

-1

Step-by-step explanation:

(2/3)³ × (2/3)⁻⁶=(2/3)²ˣ⁻¹

⇒ (2/3)³⁺⁽⁻⁶⁾ = (2/3)²ˣ⁻¹                               - [ As xᵃ * xᵇ  = xᵃ⁺ᵇ]

⇒ (2/3)⁻³ = (2/3)²ˣ⁻¹  

⇒  -3 = 2x-1                                                 - [As, if xᵃ = xᵇ ⇒ a=b]  

⇒ x = -1.
