Question

if (2.3)×=1000 than find the value of 1/×-1/y
​

Answer 1

Answer:

hi dear friend

Given that,

2.3^x=0.23^y=1000

Now,

2.3^x=1000 and 0.23^y=1000

Applying log on both sides we get,

log2.3^x=log1000

xlog2.3=log10^3

xlog(23/10)=3

log(23/10)=3/y..1

and,

log0.23^y=log1000

ylog(23/100)=log10^3

ylog(23/100)=3

log(23/100)=3/y2

By eq1-eq2 we get,

log(23/10)-log(23/100)=3/x-3/y

log{(23/10)/(23/100}=3(1/x-1/y)

log10=3(1/x-1/y)

1=3(1/x-1/y)

1/3=1/x-1/y.

Hence value of 1/x-1/y=1/3.
