Simplify the following expression: ( (x^5) / (x^2) ) ^ 4

For this question it is key to remember the indices laws. The ones you need to recall for this question are: x^a / x^b = x^{a - b}, and (x^a)^b = x^{a * b}.
Using these laws, we can simplify the expression in question: ( x⁵ / x² ) ⁴ = ( x³ ) ⁴ = x¹². And so the solution is x¹².
