Best ResponseYou've already chosen the best response.0okay \[3^{2}  3^{3}\]

Best ResponseYou've already chosen the best response.0Ok, to do this you will need to factor a bit. Do you know how to factor?

Best ResponseYou've already chosen the best response.0Ok, so we can rewrite this expression like this: \[3^2  3^3 = 3^2  (3^2*3)\] Right?

Best ResponseYou've already chosen the best response.0Now factor out a \(3^2\) from each term, and what do you get?

Best ResponseYou've already chosen the best response.0No. \[3^2  3^2(3) = 3^2(\frac{3^2}{3^2} \frac{3^2( 3)}{3^2}) = 3^2(13)\]

Best ResponseYou've already chosen the best response.0Recall how to factor something 5(3) + 5(100) = 5(3+100) = 5(103)

Best ResponseYou've already chosen the best response.01717(23) = 17(123) = 17(22)

Best ResponseYou've already chosen the best response.0Or if you prefer you can think of it the other way. \[3^2  3(2^2) = 1(3^2)  3(3^2) = 2(3^2)\]

Best ResponseYou've already chosen the best response.0Ack.. that should be \[3^2  3(3^2)\] before the first equals

Best ResponseYou've already chosen the best response.0Ok lets try this a different way. Forget what I said before. Ok

Best ResponseYou've already chosen the best response.0\[3^2  3^3\] \[= 1(3^2)  3(3^2)\] With me so far?

Best ResponseYou've already chosen the best response.0Do you see how these two things are equal?

Best ResponseYou've already chosen the best response.0Ok, so now I tell you, you have 1x and you subtract 3x, what will you have?

anonymous

Best ResponseYou've already chosen the best response.0So here, you have \(1(3^2)\) and you subtract \(3(3^2)\), what will you have?

anonymous

Best ResponseYou've already chosen the best response.0Well yes, but that's not an expression with 1 exponent.

anonymous

Best ResponseYou've already chosen the best response.0Although you could write it as \(18^1\) if you want to be a smart retrice;p

anonymous

Best ResponseYou've already chosen the best response.0I think they want you to write it as \(2(3^2)\)

anonymous

Best ResponseYou've already chosen the best response.0I could be wrong though.

Best ResponseYou've already chosen the best response.0Wait a minute, that is not correct

anonymous

Best ResponseYou've already chosen the best response.0It's 18 or \(2(3^2)\). It's the same number, it just depends on how your teacher wants to see it.
