Answer 2

Answer:

Step-by-step explanation:

First i will tell you the answer in brief...

25 is the square of 5.. so 5^2 = 25

and 1/9 = (1/3)^2

NOW ANSWER:-

the equation can be written as:-

5^2(x-1) = 5^y+1

= 5^2x-2 = 5^y+1

Now as 5 is the common base..

so we can write it as

2x-2 = y+1 (These are the exponents)

2x-y-2-1 = 0

2x-y-3 = 0

Final Answer of i part :- 2x-y-3

ii part

1/3^3-x = 1/3^4y

3-x = 4y

-x-4y+3 = 0
