@ ADITYA HOW IT CAN BE LOG(360) ? @ PARUL The question might be the number of classes because, the length of the class and class interval are one and the same. If so, The first class should include the smallest item (44) and the last class should include the largest item (73) One of the principles of classification is that the first class/lower limit of a class should start with 0 or a multiple of 5 Therefore, considering the above and assuming the length of the class as 5, the classes will be 40-45, 45-50, 50-55, 55-60, 60-65, 65-70, 70-75 Number of classes = 7

@ Gaurav - I mean 2^3x 3^2x 5^x/log 360

Int. oa^x = a^x/log a

2^3x 3^2x 5^x

= Int. 8^x 9^x 5^x

=Int. 360^x

=360^x /log 360 or 2^3x 3^2x 5^x/log 360

@ Aditya, Can't we just solve lyk this

 

integrate (2^3x)(3^2x)(5^x) 

step 1:  { 2^3x/log(2).3 } { 3^2x/log(3).2 } { 5^x/log(5) }

step 2:  (2^3x)(3^2x)(5^x)/log(180) + c

you've applied the formula correctly, but method is wrong :)

and one thing

(loga + logb + logc) = (log abc), but
(loga. logb. logc) is not equal to (log abc)

my method is correct, how can you make 2^3x=8^x as 3x is in power, u cannot cube 2.
