Best ResponseYou've already chosen the best response.1if x = 3, y = 5, z = 3 The expression would be shown as (3)3  2(5)\[(3)^{3}  2(5)^{2}  3(3)^{3} + 3^{4}\]2

Best ResponseYou've already chosen the best response.1ight ight (: so you know how the question tells you what number the variables mean? like x = 3, y = 5, z = 3 well, all you gotta do next time, is rewrite it on a piece of paper and basically substitute the variables to the numbers that the question listed. and if there's any powers, you multiply, and if there's any in parenthesis, you include that number in with what you're multiplying. is this making sense ? @shadow2239

Best ResponseYou've already chosen the best response.0so if it was 2 (5) ^2 I would add 2 +5 and do 6^2 ????

Best ResponseYou've already chosen the best response.1No, shadow. You would multiply, 2(5) means to multiply because they're close together and there's really nothing there to prove that you have to add. and well...since 2 x 5 equals 10, you multiply 10 twice.

Best ResponseYou've already chosen the best response.1because it has a power of 2.

Best ResponseYou've already chosen the best response.0so it would be 20 then ?

Best ResponseYou've already chosen the best response.1no no \[10^{2}\] does not mean 10 x 2 it means, 10 x 10. you're multiplying 10 TWICE not by two. :c
