Show that underroot 4 is irrational number |
|
Answer» Step-by-step EXPLANATION: Say 4–√ is rational. Then 4–√ can be REPRESENTED as ab, where a and b have no common factors. So 4=a2b2 and 4B2=A2. Now a2 must be divisible by 4, but then so must a (fundamental theorem of arithmetic). So we have 4b2=(4k)2 and 4b2=16k2 or even b2=4k2, which implies that b=4n by the fundamental theorem. Now we have a contradiction (since can note that both a and b are divisible by 4 and we assumed they were coprime) This proof is clearly false, YET I fail to see where it differs. Where does it do so? |

.2 men and 5 boys can finish a piece of work in 4 days, while 3 men and6 boys can finish it in 3 days. Find the time taken by one man alone tofinish the work and that taken by one boy alone to finish the work. |
|
Answer» Step-by-step EXPLANATION: let the time taken by one MAN be=x and by one boy be=y then the EQUATIONS formed will be eq1: 2/x+5/y=1/4 eq2: 3/x+6/y=1/3 so by solving eq1 we get, eq3: 8x+20y=xy and by solving eq2 we get, eq4: 9x+18y=xy now, subtract eq3 by eq4 we get, x-2y=0 eq5:=》y=x/2 substitute eq5 in eq4 we get, 9x+9x=x × x/2 then,=》18x=x × x/2 =》18x×2=x × x =》36x=x × x =》36=x × x/x eq6:36=x now, substitute eq6 in eq4 we get, 324 + 18y=36y now, 324=36y-18y =》 324=18y =》324/18=y =》18=y therefore the time taken by one man =36 DAYS and that by one boy =18 days |
