is this (4)^1/3 or 2^1/3 * 2^1/3 = 4^2/3

anonymous · Answer

Is 1/3 the exponent? or is it a 2?

anonymous · Answer

1/3 is the exponent

anonymous · Answer

$$(2 *2)^{1/3}$$

anonymous · Answer

Always remember PEMDAS. Parentheses before exponents.
So (4)^1/3

anonymous · Answer

but then why is this true: (xy)n = x^ny^n

anonymous · Answer

$$(xy)^{n} = x ^{n} y ^{n}$$

anonymous · Answer

It says this in a book or something, correct?

anonymous · Answer

i thought the same thing- PEMDAS, but yet that changes the answer...i think.

anonymous · Answer

This is because the exponent is a variable which distributes into the parentheses.

anonymous · Answer

i see- with numbers you actually solve and with variables you can't, so you distribute?

anonymous · Answer

Yes, do you have the answer to your problem? Maybe I can help you get there.

anonymous · Answer

no, i don't.  thank you- you were very helpful.
