Monkey in the Human shadow

Nawa ooo.........What of SHOE POLISH n SAWDUST.........to rise n shine

Head Boy or Guarantor......

omolizzy: I won't oppose u bt if u do medicine or related courses in Bayero uni kano u go know say monkey n gorilla na different specie dem b

Yes ooooo....B.U.K no be beans.....@Lizzy wat dep't re U? M frm maths dep't

Could this be it? If this can be followed to logical conclusion, I think this will be the end of teenagers' suicide bombing, provided our security are ready for it

Oga, park well oooo.......stop dey lie give ppl for here....it happened at a mosque just a stone throw away frm my house at tudun wada in funtua, no explosive issues was involved..................No insult intended

efficiencie: If a ≥0 ,b ≥0 ,c ≥0 ,d≥0,
show that:
(abcd)^(1/4) ≤ (a+b+c+d)/4

If a ≥0 ,b ≥0 ,c ≥0 ,d≥0

Then

(√a - √b)^2 ≥ 0

a + b ≥ 2√ab

(a + b)/2 ≥ (ab)^(1/2) ...1

similarly it can be argued that:

(c + d)/2 ≥ (cd)^(1/2) ...2

And using d rule
if x,y,u,v are non negative and x≥y and u≥v then xu≥yv

Hence from 1 and 2 usin d abov rule:

(a+b)(c+d)/4 ≥ (abcd)^(1/2)

Apply d rule:
If u≥v and u,v are non negativ then u^x≥v^x wen x≥0

Hence

√((a+b)(c+d))/2 ≥ (abcd)^(1/4)

(abcd)^(1/4) ≤ √((a+b)(c+d))/2 ...3

Using d rule: 2√uv ≤ u+v
whr u,v are non negative
and hence d RHS of inequality 3 is given as:

√((a+b)(c+d))/2≤(a+b+c+d)/4 ...4

On apply d law of transitivity
If u≤v and v≤w then u≤w

Hence on combinin d results frm 3 n 4:

(abcd)^(1/4) ≤ (a+b+c+d)/4

Quod Erat Demonstrandum

@Lord efficiencie, Long live thee.......I do really appreciate U, though I still ve few other questions that requires solution, permitt me to send it................Maths is really fun

Pls pals, help me with this questionn it is very urgent pls..................

If a,b,c,d>=0, show that (abcd)^1/4 <= (a+b+c+d)/4................

God bless us all and I salute evEryone here.....................
