Answer 1

Answer:

hh

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

Answer 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
