sir i have a doubt in question 22 i.e integral of 1/xdx,LL=-4 AND UL=-1.sir the integral is log x and log x is not defined for x<0 and therefore area under -4 and -1 is not defined.so shouldnt be the answer be undefined?

nd sir i am not able to approach question17,19,23,all of them are based on maximizing over all possible values,can u please solve any one of these questions.
q.17What is the maximum value of a(1-a)b(1-b)c(1-c), where a, b, c
