Question

Find the value of X in each of following. ​

Answer 1

Answer:

x=4

Step-by-step explanation:

since base is same i.e. 7/9

therefore power gets added up

so, 3+6 = 2x-1

      9 = 2x-1

      2x = 8

       x = 4

Answer 2

Answer:

(7/9)3 * (7/9)6 =(7/9)2x-1

(7/9) 3+6=8=(7/9)2x-1

(7/9)9 =(7/9)2x-1
