Respuesta :
Values of a and b should be used is a = 6 and b = 4 so Option A and Option D.
Given:
The difference of cubes identity will be used to determine the difference between 216 and 64.
a^3-b^3=(a-b)(a^2+ab+b^2).
a^3 - b^3 = 216 - 64 = [tex]6^{3} -4^{3}[/tex] = 152.
On comparing a = 6 and b = 4.
= (a-b)(a^2+ab+b^2).
= (6-4)(6^2+6*4+4^2)
= 2(36+24+16)
= 2(76)
= 152.
a^3-b^3=(a-b)(a^2+ab+b^2).
Therefore values of a and b should be used is a = 6 and b = 4 so Option A and Option D.
