Let's say you have $(x^8)*(x^3)$ In this case, you add the exponents $(x^8)*(x^3)=x^{11}$ If you have $\frac{x^8}{x^3}$, you subtract. $\frac{x^8}{x^3}=x^5$ If you raise a power to a power, you multiply: $(x^8)^{3}=x^{24}$

also when you take the square root, you divide by 2, say it were the square root of x^12, it would be x^6 because x^6 times x^6 = x^12 because you add the exponents
