sarah mosy:

x^2(x-2)



ok first things first i think it would have been good manners to put a question in there somewhere considering humans and not calculators are answering this

secondly what are you trying to say?
cases: you are saying:

a: (x^2)*(x-2)

or

b: (x)^(2*(x-2))

if you don't see the difference between these look up how parentheses and order of operations works

doing something with both:

a: (x^2)*(x-2) = (x^3)-2(x^2)

b:

-one of the laws of exponents is when take a number with an exponent to another exponent, you multiply the two exponents together
therefore,
(x)^(2*(x-2)) = [ x^2 ]^(x-2) or [x^(x-2)]^2

note that it may be hard for you to "intuitively understand" or "visualize" what it means to take an exponent to a fraction or a variable... just kinda think on it for a bit

look at (x^(x-2)):
--another law of exponents is when you multiply two of the same number/variable with different exponents, you add the exponents.
therefore,
(x^x) * (x^(-2))

so there's the answer to the question you didn't ask
