Solve the equation:

[tex] 125^{2x} \cdot 625 = 125^{3x} [/tex]

Answer :

Let's solve the equation step-by-step:

We start with the given equation:

[tex]\[ 125^{2x} \cdot 625 = 125^{3x} \][/tex]

The first step is to express 625 as a power of 125. We know that:

[tex]\[ 625 = 125^2 \][/tex]

Substituting this into the equation, we have:

[tex]\[ 125^{2x} \cdot 125^2 = 125^{3x} \][/tex]

Now, we can use the property of exponents:

[tex]\[ a^m \cdot a^n = a^{m+n} \][/tex]

Applying this property to the left side of our equation gives:

[tex]\[ 125^{2x + 2} = 125^{3x} \][/tex]

Since the bases are the same, we can set the exponents equal to each other:

[tex]\[ 2x + 2 = 3x \][/tex]

Next, we solve for [tex]\( x \)[/tex]. Subtract [tex]\( 2x \)[/tex] from both sides:

[tex]\[ 2 = 3x - 2x \][/tex]

This simplifies to:

[tex]\[ 2 = x \][/tex]

Therefore, the solution to the equation is [tex]\( x = 2 \)[/tex].
