5 0

Answer:

x = 1

Step-by-step explanation:

625 =  {5}^{6 - 2x}  \\  \\  \implies \:  {5}^{4}  =  {5}^{6 - 2x}  \\  \\ (bases \: are \: equal \: so \:  \\ exponents \: will \: also \: be \: equal )\\  \\  \implies \: 4 = 6 - 2x \\  \\  \implies \: 2x = 6 - 4 \\  \\   \implies \: 2x = 2 \\  \\   \implies \: x =  \frac{2}{2}  \\  \\   \implies \:  \huge \red{ \boxed{x =1}}\\  \\
