http://www.wolframalpha.com/input/?i=simplify+%28square+root+x^3%29+divided+by+%28cube+root+x^4%29

the first input thing id what im trying to figure out, simplify (square root x^3) divided (cube root x^4). i know the answer obviously but i don't know how to work that out. if someone could explain it to me that would be AWESOME (grade 10 math so nothing too in depth)

[(x^3)^1/2]/[(x^4)^1/3]

x^9/6/x^8/6

x^1/6

I think

[x^(3/2)]/[x^(4/3)]
[x^(9/6)]/[x^(8/6)]
(9/6)-(8/6)=1/6
x^(1/6)

sqrt x^3/crx^4
(x^(2/3))/(x^(3/4))
(x^(2/3))*(x^(-3/4))
x^(-6/12)
x^(-1/2)
1/2x

Wrong. Say x=1.

LS=[sr(1)^3]/[cr(1)^4]
LS=[sr(1)]/[cr(1)]
LS=1

With your answer:

RS=(1/2)(1)
RS=1/2

Thus LS does not = RS.

With the correct answer:

RS=1/(1)^6
RS=1

Therefore LS = RS.

I haven't taken math in 5 years and it's great. The sad thing is, I used to be really good at math. Tested into calc 3 my freshman year of college. Fuck math.

I have nothing to contribute to this thread besides to claim that I haven't taken math in 3 years and don't ever need to again.
