Could someone please explain to me why this is true:

5^2/3x25^2/3=25 I understand problems like 5^4+5=5^5 is false, but it's simpler. I'm just not getting what makes the top problem true

You need to use parentheses in your problem

5^2/3x25^2/3=25

I have no idea what this means?

Is this your problem?

5^2/3 x 25^2/3 = 25

This does not equal 25.

For the above to be true you will have to write it s

(5^(2/3)) (25^(2/3))

= (5^(2/3))(5^(4/3))

= 5^(6/3)

= 5^2

= 25

thanks REINY. After seeing your post, the problem, as I typed without parentheses, is apparent. I don't know why I didn't see that! Parentheses are nice though.
