```							taking logĀ  base5 on both sides we will get equation aslog5x +log5x+1 =log125now the equation can be written as xlog5+xlogx+1=3log5by cancelling log on both sides we will get x+x+1=32x+1=32x=2x=1

```							Sol:- 5^x+5^(x+1)=125  5^x+x+1=125.   (a^mĆa^n=a^m+n)5^2x+1=5^3 .       (125= 5Ć5Ć5=5^3) 2x+1=3. ( By dividing 5  in both term)2x=3-12x=2.   (By dividing 2 in both term)So, the value of x = 1
