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^24a+5/a^24a+4
a. 6a16/(a+2)(a2)^2
b. 6a+4/(a+2)(a2)^2
c. 6a16/(a+2)(a2)
d. 6a+4/(a+2)^2(a2)
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/m8 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/m8
b. 5m5/m8
c. 5m37/m8
d. 5m+43/m8
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/y10/ +y 25/y10
a. 1/y5
b. 1/y+5
c. 6/y+25
d. 1/y+1/5
5. Simplify the compound rational expression. Use either method. 2/a1/3/4/a^21/9
a. a+3/3
b. a3/3
c. 3a/6+a
d. 3a/6a
6. Compute as indicated. Write final results in lowest terms. x^2+2x15/2x6 Divide by x^225/4x^2
a. 2x^2/x3
b. 2x^2/x+3
c. 2x^2/x5
d. x5/2x^2
Thanks again for all the help its helping me!
