Why isn't matrix multiplication commutative?

I don't even understand what the question is asking.

Definition: The average rate of change of a function f(x)f from x=a to x=b is the slope of the line which passes through (a,f(a) and (b,f(b)). Consider the function f(x)=x^2+6 and...

Use an algebraic method to find the cube roots of the complex number: 5(cos(π/6)+isin(π /6)) The answer needs to be in a+bi form.

Use De Moivre's Theorem to find the indicated power of the complex number: (- √3+i)^6 Type the answer in a+bi form.

The answer should be rounded to nearest whole number (if needed)
