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

mathslover Group TitleBest ResponseYou've already chosen the best response.1
226/4 = remainder = 2 that is we have 9

Like rationalizing factor? and magic square?
 one year 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?
 one year 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?
 one year 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 = \(\sqrt{3}2\)
 one year 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 \(\frac{\sqrt{2}}{2}\)
 one year 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
 one year 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
