i need some help on these math problems?

Question

I HAVE TO FIND THE PRODUCT: its polynomials functions/ exponents
1.(r+3) to the 4th power the four is outside the parenthesis
2.(z-3) to the 3rd power the three is outside the parenthesis
3.(q-2) to the 4th power the four is outside the parenthesis
4(x+3y) to the 3rd power the three is outside the parenthesis

Answer 1

1. (r + 3)^4 rewrite it into 4 factors

(r + 3)(r + 3)(r + 3)(r + 3) multiply the first the two and last two using the FOIL method

(r^2 + 6r + 9)(r^2 + 6r +9) multiply those together

r^4 + 6r^3 + 9r^2 + 6r^3 +36r^2 + 54r + 9r^2 + 54r + 81 combine like terms

r^4 + 12r^3 + 54r^2 + 108r +81


2. same as the first, rewrite into 3 factors, then use FOIL.
(z - 3)(z - 3)(z - 3)

z^2 - 6z +9 (z - 3)

z^3 - 6z^2 + 9z - 3z^2 + 18z - 27 combine like terms

z^3 - 9z^2 + 27z - 27


3. same as the first

4. again, same methods. use FOIL
(x + 3y)(x + 3y)(x + 3y)

(x^2 + 6xy + 9y^2)(x +3y)

x^3 + 6x^2y + 9xy^2 + 3x^2y + 18xy^2 + 27y^3 combine like terms

x^3 + 9x^2y + 27xy^2 + 27y^3

Answer 2

Your rimind me in my childhood and school i miss these easy question, it is just like asking how many hairs do you u have in your head ... lol i am drunk

Answer 3

1) r^4+12r^3+54^2+108r+81

2)z^3-9z^2+27z-27

3)q^4-8q^3+24q^2-32q+16

4)x^3+9yx^2+27y^2x+27y^3

Answer 4

i think it is save to say that I am not smarter than a 5th grader!

Answer 5

well I was gonna answer but I think you've already got it.
