- 1/log3(60)=log3/log60========>1
1/log4(60)=log4/log60========>2
1/log5(60)=log5/log60========>3
thus 1+2+3=(1og3+log4+log5)/log60=log(3*4*5)/log60=log60/log60=1
so ans is 1

- i can't get the question i worked still i am absorbed
(reciproc(log(4)) + reciproc(log(5)) + reciproc(log(3)))*60
5.1875438798064588289018338055301 * 60
ie. ans= 311.25263278838752973411002833181

- reciprocal is log60 3+log 60 4+ log60 5
= log60(3*4*5)
= log60 60 = 1
