# Differentiate the functions given in w.r.t. x.(x + 3)2. (x + 4)3. (x + 5)4

Given: (x + 3)2. (x + 4)3. (x + 5)4

Let y= (x + 3)2. (x + 4)3. (x + 5)4

Taking log on both sides, we get

log y = log((x + 3)2. (x + 4)3. (x + 5)4)

log y = log(x + 3)2 + log(x + 4)3 + log(x + 5)4

log y = 2.log(x + 3) + 3.log(x + 4) + 4.log(x + 5)4

Now, differentiate both sides with respect to x

= (x + 3)(x + 4)2(x + 5)3(9x2 + 70x + 133)
