    [tex]625 = 5^{7x-3} \\[/tex]

    Create equivalent bases:

    [tex]625 = 5^4\\5^4 = 5^{7x-3}[/tex]

    Since the bases are equal, then exponent1 = exponent2 in order for this equation to be true.

    [tex]7x - 3 = 4\\7x = 7\\x = 1[/tex]

    Check the

    [tex]5^{7(1) - 3}\\5^{7 - 3}\\5^4\\625 = 625[/tex]

    Our answer is correct,

    x = 1

    A. x = 1

    Step-by-step explanation:

    [tex]5^{7x-3}=625\\\\5^{7x-3}=5^4\iff7x-3=4\qquad\text{add 3 to both sides}\\\\7x=7\qquad\text{divide both sides by 7}\\\\x=1[/tex]
