(5 2/3)^1/2 is the problem 5 1/3 is the answer and I've checked a ton of sites and examples in the book and none of them tell me how to get that answer, they all come out either 5 1/6 or 1.709975. If anybody knows how to do this right could you please tell me?? :confused: :confused: :confused:

thanks,
Kylie.

Is that the square root of five and two thirds? If so, write it as 17/3

\sqrt{\frac{17}{3}}=\frac{\sqrt{51}}{3}\approx{2.3 8

The answer is not five and one third or any of those others listed.

Who knows. I doubt if we hear back from them anyway.

I think I see what's going on. I think what Kylie meant to write is:


(5^ {\frac 2 3}) ^ {\frac 1 2}

which would be equal to 5^1/3 = 1.709975...

Kylie: whenever you have (a^b)^c you multiply the exponents to get a^{bc}. Here a = 2/3 and b = 1/2, so (5^ {\frac 2 3}) ^ {\frac 1 2} \ =\ 5^ {\frac 1 3} . Hope this helps.
