Answer :

To solve the equation [tex]\( 625 = 5^{6 - 2x} \)[/tex] for the variable [tex]\( x \)[/tex], we will proceed with the following steps:

1. Express both sides with the same base: \\
Notice that 625 can be written as a power of 5:
[tex]\[ 625 = 5^4 \][/tex]
Therefore, the equation becomes:
[tex]\[ 5^4 = 5^{6 - 2x} \][/tex]

2. Set the exponents equal to each other: \\
Since the bases are the same and the exponents must be equal for the equation to hold true, we set the exponents equal:
[tex]\[ 4 = 6 - 2x \][/tex]

3. Solve for [tex]\( x \)[/tex]: \\
To isolate [tex]\( x \)[/tex], we perform the following steps:
[tex]\[ 4 = 6 - 2x \][/tex]
Subtract 6 from both sides:
[tex]\[ 4 - 6 = -2x \][/tex]
Simplify:
[tex]\[ -2 = -2x \][/tex]
Divide both sides by -2:
[tex]\[ x = 1 \][/tex]

4. Conclusion:

The value of [tex]\( x \)[/tex] that satisfies the equation [tex]\( 625 = 5^{6 - 2x} \)[/tex] is [tex]\( \boxed{1} \)[/tex].
