The base is 5 because when you divide 31.5 by 6.3 it's 5
The first step to simplify this equation is to multiply the numbers
1512
![x^{4}](https://tex.z-dn.net/?f=%20x%5E%7B4%7D%20)
×
![x^{7}](https://tex.z-dn.net/?f=%20x%5E%7B7%7D%20)
next,, youll multiply the terms with the same base by adding their exponents
1512
![x^{4+7}](https://tex.z-dn.net/?f=%20x%5E%7B4%2B7%7D%20)
finally,, youll add the numbers together
1512
![x^{11}](https://tex.z-dn.net/?f=%20x%5E%7B11%7D%20)
since you cant simplify any further,, the correct answer to your question is 1512
![x^{11}](https://tex.z-dn.net/?f=%20x%5E%7B11%7D%20)
