Question

find the value of n in the above question
​

Answer 1

Answer:

Step-by-step explanation:

25^n-1+100=5^2n-1

100=5^(2n-1) - 25^(n-1)

100=5^2n/5 - 25^n/25

100=25^n/5 - 25^n/25

100=25^n(1/5-1/25)

100=25^n(5/25-1/25)

100=25^n[(5-1)/25]

100=25^n(4/25)

100×25/4=25^n

25×25=25^n

25^2=25^n

n=2

Hence,n=2
