6) For what values of k is 5x+ky=3 parallel to 2x-3y? For what values of k are the two lines perpendicular?

13) Remembering that for even functions f(-x)=f(x) and that for odd functions f(-x)=-f(x) show whether the following functions are even, odd or neither
a. y=x^4
b. y= x-x^4
c. y= 1/((x^2) -4)
d. y= -2(x^3) +4x

21) Simplify each of the following
a. ((2/3)x^(-3))(15x^7)
b. (x^3)((2yz^2)^3)
c. ((3(x^3))(4(x^5))) / ((x^2)^3)
d. ((2(y^4))((3(y^2))^2)) / ((y^3)^4)
e. (3(a^(-2))(b^3))^(-3)

22 )Simplify by removing all possible factors from the radical
a. sqroot (9(a^8)b)
b. cubed root (24(a^4)(b^8))
c. sqroot (75 / (a^6))

23) Factor each of the following completely
c. 4(x^16) -9(y^6)
d. 6(x^2) + 7x - 20
e. 3(x^2) -5x + 2
h. (x^2) +4x + 4 + 9(y^2)

Additional Details:
I'm not really just wanting answers.. as it says i just need someone to remind me how to do these... so i can do them.. i have already learned all this just forgotten how to do it

part 1
By using the substitution u= sqroot(x+3), find the integration of (e^sqroot(x+3))/sqroot(x+3) wrt x.

part 2
Hence evaluate the integration of e^sqroot(x+3) wrt x, with integrals 0 to 1, giving ur answer in exact form.

Part 2 is the only part i need help in. so any help, even just by pointing me in the right direction would be appreciated. thanks

Is 0^0 accepted as 1?
I saw a question, which asks for the interval of convergence of the series Sigma x^n, n= 0 to n = oo
It diverges for all x different from zero, but then I got confused about x = 0. Can the question ask for sigma x^n staarting at n = 0?

all of my friends at school says im smart and put this unwanted pressure on me to excel in every class but I spend 7 hours each day studying. my school ends at 2:30 pm and I get home at about 3:00 pm. I study from 3 to 10 and sometimes longer than that. if they study that much they could make the same grade as me...so am i smart or do I study a lot?
