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:

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

3/4 of a number minus -16 equals 28. What is the number ?

Zigmanuir [339]

Answer:

The number is 16

Step-by-step explanation:

3/4 n- (-16) = 28

3/4 n + 16 = 28

Subtract 16 from each side

3/4 n +16-16 = 28-16

3/4 n =12

Multiply by 4/3 to isolate n

4/3 * 3/4 n = 12 * 4/3

n = 16
