 \frac{5 {}^{2x - 1} }{25}  = 5 {}^{3}  \\  \frac{5 {}^{2x - 1} }{5 {}^{2} }  = 5 {}^{3}  \\ 5 {}^{2x - 1 - 2}  = 5 {}^{3}  \\ when \: bases \: are same \: we \: equate\: the \: \: the \: powers \\ 2x - 1 - 2 = 3 \\ 2x - 3 = 3 \\ 2x = 3 + 3 \\ 2x = 6 \\ x =  \frac{6}{3}  = 2

Answer:

x=1

Step-by-step explanation:

5^2x+1÷25=125

5^2x+1÷5^2=5^3

when base is same then power is also same.

2x+1-2=3

2x-1=3

2x=3-1

2x=2

x=2/2

x=1
