If x2=7x^2=7x2=7, what is the value of (x+3)3−(x−3)3?(x+3)^3-(x-3)^3?(x+3)3−(x−3)3?
Simplify
(2+3)3+(2−3)3. ( 2 + \sqrt{3})^3 + ( 2 - \sqrt{3})^3. (2+3)3+(2−3)3.
If 8x3−512y3=(2x−ay)(bx2+cxy+dy2),8x^3-512y^3=(2x-ay)(bx^2+cxy+dy^2),8x3−512y3=(2x−ay)(bx2+cxy+dy2), what is the value of a+b+c+da+b+c+da+b+c+d?
(4+19)3+(4−19)3. ( 4 + \sqrt{19})^3 + ( 4 - \sqrt{19})^3. (4+19)3+(4−19)3.
