What is the approx value of W if W 1 5 11 Given log2 0 301 log 3 477 A

can anyone tell me how 10^(1.93) is calculated????????????

Ans: 86

Log W=Log(1.5^11)=11*Log(3/2)=11*( Log(3)-Log(2) )
Log W=1.936
W=10^1.936
We know 10^2=100.
So 10^1.936 will be close to and less than 100.
So by options you can get the ans as 86)

w=1.5^11
logw=(log1-log2+log3)11
logw=(0-.301+.477)11
=(.176)11
=1.986
w=10^1.986
=86(apprx)

86
take log both sides, 1.5 is 3/2
than, W=10^(log3-log2)

hey, please explain the skyscraper problem in 8th june paper

log(base 10)w = log(3/2)*11= 1.93
w= 10^(1.93)= 86 (approx) [lof base(b)a =x
then a=b^x ]

Given that W=(1.5)^11 ,log2=.301,log=.477
Taking common log on both sides,
logW=log(1.5)^11
logW=11*log(1.5) since log(x) ^a= a*log(x)
logW=11*log(3/2) => 11*(log(3)-log(2))
since log(x/y)=logx-logy
logW=11*(.477-.301)=1.936
Taking antilog on both sides,
W=86.3 (approx).
