Answer 2

Given :-  $5^{x-1} = 25^{x+1}$

Find:- x

Step-by-step explanation:-

25 can be written as $5^{2}$

so, we get new equation

⇒ $5^{x-1} = 5^{2(x+1)}$

since the base is same we can write the powers is also same

⇒ x - 1 = 2 ( x+ 1 )

⇒ x - 1 = 2x + 2

Taking x's to one side and numericals to other side

⇒ - 1 - 2 = 2x - x

⇒ 2x - x = - 1 - 2

✔ x = -3 is your answer  ✔

When coming towards exams, you must recheck the answer whether it's right or wrong ? So I will help you in rechecking also

Rechecking:-

equation ⇒ $5^{x-1} = 25^{x+1}$

Putting the value of x in the equation

⇒ $5^{(-3)-1} = 25^{(-3)+1}$

⇒ $5^{(-4)} = 25^{(-2)}$

25 can be written as $5^{2}$

So Simplifying the equation, we get

⇒ $5^{(-4)} = 5^{2(-2)}$

⇒ $5^{(-4)} = 5^{(-4)}$

Hence verified that the value of x is Correct :)
