Multiple choice question

To find the value of (28)3 + (-15)3 - (13)3, we use the formula

unknown

x3 +y3 +z3 - 3xyz = (x +y + z) (x2 +y2 -z2 -xy-yz-zx)

unknown

we calculate all the cubes and add.

unknown

we use x3 +y3 +z3 = 3xyz with x = 28, y=- 15,z= 13

unknown

we use x3 + y3 + z3 = 3xyz with x = 28,
y = -15, z = - 13
