Q. Factor completely:\newliner664s6 r^{6}-64 s^{6} \newlineAnswer:
  1. Recognize Difference of Squares: Step Title: Recognize the Difference of Squares\newlineConcise Step Description: Identify that the expression is a difference of two squares.\newlineStep Calculation: Recognize that r6r^{6} is a perfect square, as (r3)2(r^{3})^2, and 64s664s^{6} is also a perfect square, as (8s3)2(8s^{3})^2.\newlineStep Output: The expression can be written as (r3)2(8s3)2(r^{3})^2 - (8s^{3})^2.
  2. Apply Squares Formula: Step Title: Apply the Difference of Squares Formula\newlineConcise Step Description: Use the difference of squares formula, which is a2b2=(ab)(a+b)a^2 - b^2 = (a - b)(a + b).\newlineStep Calculation: Apply the formula to the expression with a=r3a = r^{3} and b=8s3b = 8s^{3}.\newlineStep Output: The factored form is (r38s3)(r3+8s3)(r^{3} - 8s^{3})(r^{3} + 8s^{3}).
  3. Factor Further if Possible: Step Title: Factor Further if Possible\newlineConcise Step Description: Check if the two resulting binomials can be factored further.\newlineStep Calculation: Recognize that r38s3r^{3} - 8s^{3} is also a difference of cubes, which can be factored using the formula a3b3=(ab)(a2+ab+b2)a^3 - b^3 = (a - b)(a^2 + ab + b^2).\newlineStep Output: Apply the formula with a=ra = r and b=8sb = 8s to get (r8s)(r2+8rs+64s2)(r - 8s)(r^2 + 8rs + 64s^2).
  4. Combine Factored Forms: Step Title: Combine the Factored Forms\newlineConcise Step Description: Combine the factored forms from the previous steps to get the final factored expression.\newlineStep Calculation: The final factored form is (r8s)(r2+8rs+64s2)(r3+8s3)(r - 8s)(r^2 + 8rs + 64s^2)(r^{3} + 8s^{3}).\newlineStep Output: The completely factored expression is (r8s)(r2+8rs+64s2)(r3+8s3)(r - 8s)(r^2 + 8rs + 64s^2)(r^{3} + 8s^{3}).
