Question

If a = 1 + log, yz, b = 1 + log zx, c = 1 + log,xy, then ab + b
(A) O
(B) 2abc
(C)abc
(D) none​

Answer 1

Given,

a=1+log yz

b=1+log zx

c=1+log xy

ab+b

1+log yz+1+log zx+1+log xy

1=log 10(we know)

log 10+log yz+log 10+log zx+log 10+log xy

taking log common,

log (10*10*10*yz*zx*xy)

log(1000*y2 z2 x2)

log 1000 y2 z2 x2

(d) none Ans
