Question

y= x^(2x+1)

find the derivative of the function using natural log

Answer 1

Log(y) = (2x+1)Log(x)

Differentiate both sides:

y'/y = 2 Log(x) + 2 + 1/x


Multiply by y:

y' = [2 Log(x) + 2 + 1/x] x^(2x+1)

Answer 2

y=x2x+1


Find the derivative of the expression.

(2x+1)


To find the derivative of 2x, multiply the base (x) by the exponent (1), then subtract 1 from the exponent (1-1=0). Since the exponent is now 0, x is eliminated from the term.

1


Since 1 does not contain x, the derivative of 1 is 0.

2x+1=2+0


Add 0 to 2 to get 2.

2x+1=2


Using the chain rule, the derivative of x2x+1 is

x2x+1*2


Multiply x2x+1 by 2 to get 2x2x+1.

2x2x+1


The derivative of y with respect to x is 2x2x+1.

The derivative of y with respect to x is 2x2x+1.
