😮
a2= ab.ac/bc= 1500
b2=ab.bc/ca=2000/3
c2=ac.bc/ab=6000
Add them all😅
You are legend I applied same and feel funny to this video
ab *bc *ca = 1000*2000*3000
=6000000000
abc =10000√60
c=abc/ab=10√60
a=10000√60/2000=5√60
b=10√60/3
a^2 +b^2+c^2
=25*60+6000/9 +100*60
=125*60+2000/3
= 7500+2000/3
=(22500+2000)/3
=24500/3
Comment please.
That's great. You are really genius
a=3k. b= 2k
ab =6k^2=1000
k =10√5/√3
Now
a^2 + b^2 + c^2
= (a +b +c) ^2 -2(ab+bc+ca)
=(11k) ^2 -2(6000)
=121*100*5/3-12000
=(60500-36000)/3=24500/3
