Best ResponseYou've already chosen the best response.1when you multiply same bases you should `add` their exponents

Best ResponseYou've already chosen the best response.0okay i remember here is rule a while ago but i cant remember it that well.

Best ResponseYou've already chosen the best response.1alright so when we multiply same bases we should add their exponents \[\huge\rm x^m \times x^n=x^{m+n}\]

Best ResponseYou've already chosen the best response.1i is same as i to the one power so \[\huge\rm i^1 \times i^1=??\]

Best ResponseYou've already chosen the best response.0the thing i guess that is confusing me is the fact that my problem does not contain exponents. The i thing does sort of make sense.

Best ResponseYou've already chosen the best response.1no there is an exponent `invisible one`

Best ResponseYou've already chosen the best response.0so my negative i should be squared then your suposed to take (1) (i) i^2

Best ResponseYou've already chosen the best response.0to make it with out its exponent

Best ResponseYou've already chosen the best response.1multiply i times i which is i^2 and i^2 =what ?

Nnesha

Best ResponseYou've already chosen the best response.1\[\large\rm i=\sqrt{1}~~~~~~~so~~i^2=?\]

Best ResponseYou've already chosen the best response.0so is it just 1? im still confused

Nnesha

Best ResponseYou've already chosen the best response.1you should remember 4 cycle of i \[\rm i=\sqrt{1}\]\[\rm i^2=1\] \[\rm i^3=i\]\[\rm i^4=1\]

Best ResponseYou've already chosen the best response.0so the answer should be 63?

Best ResponseYou've already chosen the best response.1if you know that then you can find i^999

Best ResponseYou've already chosen the best response.1it's dw:1441043195360:dw i times 1 forgot the negative

Best ResponseYou've already chosen the best response.1dw:1441043278896:dw i^2=1 now distribute (1) then combine them

Best ResponseYou've already chosen the best response.1you gotta be careful about signs especially negative

Best ResponseYou've already chosen the best response.0so 64 (1) = 64+1 = 65

Best ResponseYou've already chosen the best response.0nope lol im not in calculus i wish i knew calculus it would give me an advantage im in a math prep for college and then im in an actual college class that will adventually teach us calculus.

Best ResponseYou've already chosen the best response.0ill be on later im gonna attempt to work on some of these by my self now the foil with the i is still a bit confusing though.

Best ResponseYou've already chosen the best response.0the prob was (2+7i)^2 and they want me to use foil i got 4+77i which is not correct

Nnesha

Best ResponseYou've already chosen the best response.1(2+7i)^2 is same as (2+7i)(2+7i) now foil!

anonymous

Best ResponseYou've already chosen the best response.0okay im gonna go step by step with how i got 4+77i

Best ResponseYou've already chosen the best response.0okay so instead it is 4+28i+49 then i would add the 4+49 = 53+28i?

Nnesha

Best ResponseYou've already chosen the best response.1no it's \[\huge\rm 4+28i+49i^2=4+28i+49(1)\] 49 is positive before u distribute by negative on

anonymous

Best ResponseYou've already chosen the best response.0ah okay the signs get me again. then this should be 45+28i
