${25}^{n - 1} + 100 = {5}^{2n - 1}$
find the value of (n)​

Answer 1

Answer:

The Value of n is 2.

it has to be solved by linear equation.

Step-by-step explanation:

5^(2n-2)-5^(2n-1)+100=0

or,5^2n/5^2-5^2n/5+100=0

Let x=5^2n....i

now put X in place of 5 to the power 2 n solve the linear equation you will find,

x=5^4.......ii

equate the values of x from one and two and find n
