Question

Integrate dx/3x+5 :-

Kindly give proper steps.
Question no.15.

Answer 1

as we know integeration of 1/y is lny and integeration of 1/ny where n is any number is " lny ÷3 " so using this identity dx / 3x+5 =[ ln( 3x+5) ]÷ 3 + c we divide it by 3 because 3 is the coefficient of x

Hence, The integration of given function would be

I=1n(3x+5)/3+C

Answer 2

Answer : Option (c) is correct.
