Answer 1

Answer:

1 = x

Step-by-step explanation

(4/9)power 4 × (4/9) power -7 = (4/9)power 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)power-3 = (4/9)power 2x - 1 (base  same so base can be removed)

⇒-3 = 2x - 1

⇒-2 = 2x

⇒-1 = x
