Choosing the product of power property,when you multiply exponentials with the same base , you add their exponents.

This is represented as :

(x^a)*(x^b)=(x^{a+b)}

This property is true in that ;

where you have x³ × x³ , x³ is x*x*x and the other x³ is x*x*x .Adding the xs will give x⁶ which is similar to 3+3=6 xs
