Hope u like my process
======================
 {(5)}^{2x - 1}  -  {(25)}^{x - 1}  = 2500 \\ or. \:  {(5)}^{2x - 1}  -  { ({5}^{2} )}^{x - 1}  =  {25}^{2}  \times 4 \\ or. \:  5 \times {5}^{2x - 2}  -  {5}^{2x - 2}  =  {25}^{2}  \times 4 \\ or. \:  {5}^{2x - 2} ( 5 -   1 ) =  {( {5}^{2} )}^{2}  \times 4 \\ or. \:  {5}^{2x - 2}  \times 4 =  {5}^{4}  \times 4 \\  \\ so.. \\ 2x - 2 = 4 \\ or. \: 2x = 4 + 2 \\ or. \: x =  \frac{6}{2}  = 3
Hope this is ur required answer

5^(2x -1) -25^( x -1) = 2500 

5^(2x -1) -5^2(x -1) = 2500 

5^(2x -1) -5^(2x -2) = 2500

5^(2x -1) { 1 - 1/5 } = 2500 

5^(2x -1) × 4/5 = 2500 

5^(2x -1) = 25× 25 × 5 = 5^(2+2+1) 

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

2x -1 = 5 

x = 3
