eg.3^20 now see 1st 4 powers of 3 3^1=3 3^2=9 3^3=27 3^4=81 unit digits are 3,9,7,1 and after this the same pattern will be repeated.. now divide 1/4=remainder is 1 so, for remainder: 1 unit digit is 3 2 unit digit is 9 3 unit digit is 7 0 unit digit is 1 so divide 20/4 remainder is 0 so unit digit of 3^20 is 1

right is it necessary to have 4 chances ? I mean that in 3 we took : 3 , 9 , 7 and 1 in 4 we took 4

mathslover Group TitleBest ResponseYou've already chosen the best response.1
similarly for 7 we will take: 7 , 9 , 3, 1

226/4 = remainder = 2 that is we have 9

Like rationalizing factor? and magic square?
 2 years ago

King Group TitleBest ResponseYou've already chosen the best response.2
magic square is a square in which the sum of numbers in horizontal,vertical and diagonal way is the same...it is sriously tough to create one...

1 2 3 3 4 5 x y z 1 + 3 + x = 2+4+y = 3+5+z x + 4 + 3 = z + 4 + 1 1+2+3 = 3+4+5 m wrong :P well yes it is seriously tough and it involves gr8 thinking

You know rationalizing factor?
 2 years ago

King Group TitleBest ResponseYou've already chosen the best response.2
ok see rationalizing factor is like suppose u have 1/sqrt3+2 now if u multiply sqrt3 +2 by sqrt 32 u will get a rational number so sqrt3 2 is the rationalizing factor of sqrt3+2...understand?
 2 years ago

mathslover Group TitleBest ResponseYou've already chosen the best response.1
\[\large{\frac{1}{\sqrt{3}+2}}\] \[\large{\frac{\sqrt{3}2}{1}}\] Oh k so we have rationalizing factor = \(\sqrt{3}2\)
 2 years ago

mathslover Group TitleBest ResponseYou've already chosen the best response.1
for example I have : \[\large{\frac{1}{\sqrt{2}}=\frac{\sqrt{2}}{2}}\] so the rationalizing factor is \(\frac{\sqrt{2}}{2}\)
 2 years ago

King Group TitleBest ResponseYou've already chosen the best response.2
no fr 1st one yeah fr 2nd one sqrt 2 rationalizing factor is sqrt2 bcuz sqrt 2*sqrt2=2
 2 years ago

mathslover Group TitleBest ResponseYou've already chosen the best response.1
oh right so we have rationalizing factor as : 2  \sqrt{3} ?

wait asnaseer is here... if he can't do anything I will interrrupt there

King Group TitleBest ResponseYou've already chosen the best response.2
no fr 1st one i.e fr \[\frac{1}{\sqrt{3}+2}\] sqrt 3 +2 is rationalized that is it becomes a rational number when multiplied with a certain number that certain number is the rationalizing factor in this case its sqrt32
