Hope it helps you.....(✿◕‿◕✿)

Step-by-step explanation:

(4/9)^4 × (4/9)^ -7 = (4/9)^(2x-1) ​

L.H.S = (4/9)power {4+(-7)} [identity of exponent that when base are same and power are different and if they are in multiply then powers will add.]

⇒ (4/9)^-3 = (4/9)^(2x - 1) (base  same so base can be removed)

⇒ -3 = 2x - 1

⇒ -2 = 2x

⇒ -1 = x
