Okay, in this question of function is given that is fx equals to square root of lnx plus x and we have to find out the derivative of this function fx.
00:09
First of all we will rewrite it that is fx equals to we can say lnx plus x raised to the power half.
00:15
No problem.
00:16
And now we have to find out the derivative of this function so we will differentiate it with respect to x.
00:21
So it will be f dash x and the right hand side will be d over dx of lnx plus x raised to the power half.
00:30
And now we will differentiate, we will do the differentiation using the chain rule.
00:34
Okay, we will take this one variable raised to the power n and that will be 1 by 2 and this raised to the power n minus 1.
00:42
So it will be 1 by 2 and lnx plus x raised to the power n minus 1 that is 1 by 2 minus 1.
00:50
Dot differentiation of this function.
00:52
So it will be using chain rule, understand, d over d x of lnx plus x...
