$$(xy)^{3}=x ^{3}y ^{3}$$ http://www.icoachmath.com/math_dictionary/power_properties.html do you see what is missing?

anonymous · Answer

missing in your original statement...

inik this is just a question that i need to answer and if not correct i had to explain how to correct it with an example thanks for your info

anonymous · Answer

you are missing x in 3d power on right side
you have original statement:
$$(xy)^{3}=xy ^{3}$$
but it should be :
$$(xy)^{3}=x ^{3}y ^{3}$$

so to make it right you need to correct the power of x (from 1 to 3) in your original statement.

Cool?

anonymous · Answer

ok thanks in other words both sides has to be equal in order for the equatin to be correct right

anonymous · Answer

right.
it's like:
5=5 (not 5=6)
x=x
y=y (not y=3y)
