it says evaluate...

hero · Answer

So first you need to change everything to fractions.

$\sqrt[5]{8} = 8^{1/5}$
$\sqrt{8} = 8^{1/2}$
$\sqrt[3]{8^5} = 8^{5/3}$

hero · Answer

Which means what you have to begin with in fraction form is

$$\frac{8^{1/5}8^{1/2}}{8^{5/3}}$$

Which is equal to 
$$\frac{8^{1/5 + 1/2}}{8^{5/3}}$$

henrietepurina · Answer

8 and 2/10 divided by 9 and 2/3?

hero · Answer

1/5 + 1/2 = 2/10 + 5/10 
                = 7/10

So

$$\frac{8^{7/10}}{8^{5/3}}$$

hero · Answer

And now....

$$8^{7/10-5/3}$$

hero · Answer

7/10 - 5/3 should get you the correct result

henrietepurina · Answer

21/30 - 50/30 = -29/30

henrietepurina · Answer

yeah, sad but the last one was righ but the rest werent because people lied to me on here

hero · Answer

They probably made mistakes like I did. It happens. But you should learn how to check other people's computation. Everyone makes mistakes. You should make that assumption even when others are helping and double check behind them. No one else will do it for you.
