Option 1: 1236

Option 2: 488

Option 3: 536

Option 4: 1256

Team Careers360 13th Jan, 2024

Correct Answer: 1256


Solution : Substituting $x=3$ and $y=-4$ into the expression.
$64 x^3+38 x^2 y+20 x y^2+y^3$
$= 64(3)^3 + 38(3)^2(-4) + 20(3)(-4)^2 + (-4)^3$
$= 64(27) - 38(36) + 20(3)(16) - 64$
$= 1728 - 1368 + 960 - 64 = 1256$.
Hence, the correct answer is 1256.
