![### Finding Real Numbers that Satisfy the Given Equations
Below are several equations. For each, determine all real numbers \( x \) that satisfy the equation. If none satisfy the equation, select "None."
### Equations:
a. \( 5^x = 25 \)
b. \( 25^{-x} = 3125 \)
c. \( \left( \frac{9}{25} \right)^{-3x} = \frac{243}{3125} \)
d. \( \sqrt[3]{\frac{x}{7}} = 2\sqrt[3]{7} \)
e. \( x^{-\frac{2}{5}} = 3 \)
f. \( (x + 1)^2 = 3 \)
