Answer 1

Answer:

Step-by-step explanation:

(4/9)⁴ x (4/9)⁻⁷  = (4/9)²ˣ⁻ ¹

4 + (-7) = 2x - 1 ( since all the base are same,powers of LHS= powers of RHS)

- 3         = 2x - 1

  2x       = - 3 + 1

   2x      = -2

     x = -1

Answer 2

$\huge\underline\mathfrak\green{Answer}$

⇒ ${(\frac{4}{9})}^{4} × {(\frac{4}{9})}^{-7} = {(\frac{4}{9})}^{2x - 1 }$

⇒ As the bases are same 【 LHS 】 , hence power is added . 【 now equate the following question . 】

⇒ 4 + ( -7 ) = 2x - 1

⇒ -3 = 2x - 1

⇒ -2 = 2x

⇒ x = -1
