1. ## potens

Expression profile as a power of 5. If not so, then
x=?

i dont really know how to especially write 3sqrt(5) on another form :S
if i got it right i can write it like 5^1/3?

2. ## Re: potens

Numerator: 5^1 * (5^2)^3 * 5^(1/2) = 5^1 * 5^6 * 5^(1/2) = 5^(1 + 6 + 1/2) = 5^(15/2)

Let you have the fun of doing the denominator!

Yes, \displaystyle \begin{align*} \sqrt[3]{5} = 5^{\frac{1}{3}} \end{align*}

4. ## Re: potens

5^(1 + 6 + 1/2) = 5^(15/2)
idk but maybe stupid question how can that become 15/2? i cant figoure it out how u did so

Sure you know there are 15 halves in 7 and a half...

ehmm sorry but i did not understand what u mean, any way u can put it on more simple words^^? (english is my weak language)

If you had 7 and a half pies, and if you cut each of the whole pies in half, how many halves would you then have?

Sorry Petrus, but if you don't understand that 7.5 = 7 1/2 = 15/2,
then speaking to you in any language will not help: you need serious classroom help.

holy i cant finish the last one ehmm
5^1/3*5^15?

Do you not know this rule: a^x * a^y = a^(x + y) ?

Your 5^1/3 needs brackets: 5^(1/3) ; no brackets means 5^1 times 3

So 5^(1/3) * 5^15 = 5^(1/3 + 15) = 5^(15 1/3) = 5^(46/3)

WHAT does "potens" mean ?????

ty ehmm potens is on swedish i was just lazy to google translate but in english it means Exponentiation
so now i got 5^(15/2)/5^(46/3) and next i do is 5^(15/2)-(46/3)?

nvm finish it sorry for being so stupid but i am just tired and not really good on math ohh well
