to the lowest term
I posed these one's before but added parenthesis which I think made it confusing as the actually questions do not have them. So, I'm reposting them without to see if it makes sense. If not I understand.
1. Compute as indicated. Write your answer in lowest terms. a+3/a^2-4-a+5/a^2-4a+4
a. -6a-16/(a+2)(a-2)^2
b. -6a+4/(a+2)(a-2)^2
c. -6a-16/(a+2)(a-2)
d. -6a+4/(a+2)^2(a-2)
2. Use the properties of exponents to simplify the expression. Write the answer using positive exponents only. So the equation is in parenthesis. (a*b^-4/c^-7)^-3
a. ab^12/c^21
b. b^12/a^3c^21
c. b^12c^7/a^3
d. ab^12c^7
3. Compute as indicated. Write your answer in lowest terms. So this one starts with 3/m-8 then at the end next to the divide line it shows -5. The answer for A start with a negative next to the divide line.
a. - 2/m-8
b. -5m-5/m-8
c. -5m-37/m-8
d. -5m+43/m-8
4. Simplify the compound rational expression. Use either method. So this equation has a +1 before the top equation and a +y before the bottom.
+1 5/y-10/ +y 25/y-10
a. 1/y-5
b. 1/y+5
c. 6/y+25
d. 1/y+1/5
5. Simplify the compound rational expression. Use either method. 2/a-1/3/4/a^2-1/9
a. a+3/3
b. a-3/3
c. 3a/6+a
d. 3a/6-a
6. Compute as indicated. Write final results in lowest terms. x^2+2x-15/2x-6 Divide by x^2-25/4x^2
a. 2x^2/x-3
b. 2x^2/x+3
c. 2x^2/x-5
d. x-5/2x^2
Thanks again for all the help its helping me!
