Difference in areas = A1 - A2 where A1 and A2 are the areas of the larger and smaller circles. Other expressions will depend on what information about the circles is available: radius, diameter, circumference.
Area of any circle = pi*radius squared

how can exponent can make it easier to write an expression with a repeated factor in the product
You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4
I thought the answer was: 6 x 3squaredcmsquared
Area of any circle = pi*radius squared

how to write an expression letter for the study purpose?
Re-write it with a root. If the power of the expression is less than 1, for example x1/3, the expression could be rewritten as cube root of x.
