Answer:(x^{3})^5=x^{15}
Explanation:
If we have something like this (x^{3})^5, the exponential (5) means to write x^{3} five times so
(x^{3})(x^{3})(x^{3})(x^{3})(x^{3})
Gather all the exponent numbers
x^{3+3+3+3+3}
and then add
x^{15}
That's the long way
The short way is to multiply 3 by 5 and since 3 x 5 = 15 we also have x^{15}
