Answer:
k=2/3
Step-by-step explanation:
Step 1:
Step 1 in solving the exponential equations is re-writing the base same as other side of the equation
so,
![25^{3k}=625\\=> 25^{3k}=25^2](https://tex.z-dn.net/?f=25%5E%7B3k%7D%3D625%5C%5C%3D%3E%2025%5E%7B3k%7D%3D25%5E2)
Step 2:
Second step is equating the exponents
The rule used is:
![If\ B^m=B^n\ then\ m=n](https://tex.z-dn.net/?f=If%5C%20B%5Em%3DB%5En%5C%20then%5C%20m%3Dn)
So in this case
![3k=2\\k = \frac{2}{3}](https://tex.z-dn.net/?f=3k%3D2%5C%5Ck%20%3D%20%5Cfrac%7B2%7D%7B3%7D)
So the solution is:
k=2/3 ..
