x=5/3

Explanation:

Let's rewrite the right side in terms of base-10. This gives us

10^(x-1)=color(blue)(10^((2)*(2x-3))

Notice, 10^2=100, so we didn't change the value of the equation.

=>10^(x-1)=10^(4x-6)

Since we have the same bases, the exponents are equivalent. We can now set up the following equation:

x-1=4x-6

Subtracting 4x from both sides gives us

-3x-1=-6

Adding 1 to both sides, we get

-3x=-5

Lastly, dividing both sides by -3, we get

x=5/3

Hope this helps!
