Your bases are like: they are both x. When you multiply like bases with exponents, you add the exponents together to get the new power. But you can't add those til you get a common denominator. That's 20. So your problem looks like this:
![x^{ \frac{15}{20} } * x^{ \frac{4}{20} }](https://tex.z-dn.net/?f=%20x%5E%7B%20%5Cfrac%7B15%7D%7B20%7D%20%7D%20%2A%20x%5E%7B%20%5Cfrac%7B4%7D%7B20%7D%20%7D%20)
which gives you
![x^{ \frac{19}{20} }](https://tex.z-dn.net/?f=%20x%5E%7B%20%5Cfrac%7B19%7D%7B20%7D%20%7D%20)
. That's your answer!
