Simplify the problem

(x3) 5

Answer: (x^{3}) ^5=x^{15}

Step-by-step 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}

The answer to that is 15x
