Using the binomial theorem, expand the expression (4 + y) to the power of 4

Flauer [41]

Answer:

When raised to the power of 4, the binomial (4 + y) expands to:

$y^4 + 16y^3 + 96y^2 + 256y + 256$

Step-by-step explanation:

$(4 + y)^4 \\= (y^2 + 8y + 16)^2\\= y^4 + 8y^3 + 16y^2 + 8y^3 + 64y^2 + 128y + 16y^2 + 128y + 256\\= y^4 + 16y^3 + 96y^2 + 256y + 256$
