oh so.. all i have to do is multiply?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
see you need to put number of zeroes after digits and the total number of zeroes will be that which is given in power....so 1720000 ...now decimal is placed before 2 digits so put it before two zeroes 17200.00=17200
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
you have to multiply that's it
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
and general formula for multiplication in power is \[10^n= 100000000.........n\] n number of zeroes in front of 10

then but it this way one less zero in front of the digit \[10^{3}=0.001\] okay?

but i am still confused on the last one.. what was the answer for that?? 17200?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
see it's 1.72*10^(4)=1.72*10000= 1720000 then put decimal before two digits from the right it will be 17200.00
 one year ago

vikayefremova Group TitleBest ResponseYou've already chosen the best response.1
but thats not one of the options :( is it suppose to be written as 17,200?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
okay you can write it as 17,200 zeroes after decimal is of no use 17200.00=17200=17,200

workers can paint 3/4 of a house in 1 day. How many days would it take them to paint 6 houses?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
3/4= 0.75 so 0.75 house in 1 day 1 house in 1/0.75 days therefore 6 houses in \[\frac{ 1 }{ 0.75 }*6=8 days\]

do you know what is the value of \[\sqrt{27}\]
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
see 5*5=25 so sqrt 27 must be around 5 but more than that....and 6*6=36 so sqrt 27 must be between 5 and 6 clear? @vikayefremova

fencing states for perimeter of the boundary okay? so now it's a square field so let's say length of side = X therefore X*X=2000 x^2=2000 x=\[x=\sqrt{2000}=44.72\] and perimeter of square = 4*X=4*44.72=178.88 clear?

why you thought it to be 2*250 ?
 one year ago

vikayefremova Group TitleBest ResponseYou've already chosen the best response.1
because in the last problem you multiplied 4 by some number and you got the answer.. i think thats what im suppose to do here.. but im confused :/
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
oh i multiplied by 4 because it was perimeter of square that is 4 * sides
 one year ago

vikayefremova Group TitleBest ResponseYou've already chosen the best response.1
ohh right! ... hmm , well what am i suppose to do here then?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
i guess, it's kinda complex, because area of fringes is not given so i guess (side)^2=500 side=22.36 okay?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
now 4*22.36=89.44 =90 i think this should be the right choice
 one year ago

vikayefremova Group TitleBest ResponseYou've already chosen the best response.1
so it's B.? i thought it was 22? which is A.? right..?

it's B as far as i know...but probably it could be A

do you know how to tell real numbers from rational numbers?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
i think so , well every real number can be expressed as rational number let's say 'a' is a real number then in rational for it can be written as \[a=\frac{ a }{ 1 }\]
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
similarly, if you have to write some real number from rational number you can write it
 one year ago

vikayefremova Group TitleBest ResponseYou've already chosen the best response.1
okay, so then what is a irrational number?
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
numbers that can't be expressed in the form of simple fraction or any real number that can't be expressed as the ratio
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
also it cannot be represented as terminating or repeating decimals like 22/7

@vikayefremova clear?
 one year ago

vikayefremova Group TitleBest ResponseYou've already chosen the best response.1
i dont understand :/
 one year ago

ghazi Group TitleBest ResponseYou've already chosen the best response.2
let's say \[\frac{ 2 }{ 4 } and \frac{ 22 }{ 7 }\] now we can see that value of 2/4 =0.5 which ends and terminates at 0.5 after division but 22/7 = 3.14285.......it doesn't end at all so 22/7 is irrational and 2/4 is rational clear? irrational means which never terminates or never ends after numerous division
