What is the third term in the binomial expansion of (3x y3)4? 54x2y3 18x2y3 18x2y6 54x2y6.

hjlf

From the simplified form of the expression, the third term on expansion is $54x^2y^6$

Given the expression $(3x + y^3)^4$

For binomial expansion, the power of 3x will be decreasing while y^3 will be increasing.

On expansion, the resulting expression will be:

$=(3x + y^3)^4\\=(3x)^4(y^3)^0 + 4 (3x)^3(y^3)^1 + 6(3x)^2(y^3)^2 + 4(3x)^1(y^3)^3 + (3x)^0(y^3)^4\\$

Simplify the result to have:

$=81x^4+81x^3y^3+54x^2y^6+12xy^9+y^{12}$

From the simplified form of the expression, the third term on expansion is $54x^2y^6$

Iris is making hats for the members of the school marching band. She can make 3 hats in 1 1/2 hours. She wants to know how many

likoan [24]

She makes 3 hats per 1 and 1/2 hours. Therefore she makes $\frac{3}{\frac{3}{2}}$ hats per hour. This fraction simplified is 2 hats per hour. This is the solution.

2 hats per hour.
