We have been given an equation x^2 +11x=3. We are asked to complete the square for the given equation.

To complete the square for our given equation, we need to add the half the square of x term on both sides.

We can see that coefficient of x term is 11, so we need to add half the square of 11 on both sides.

(\frac{11}{2})^2  

Let us simplify (\frac{11}{2})^2.

\frac{11^2}{2^2}=\frac{121}{4}

Upon adding \frac{121}{4} on both sides, we will get:

x^2 +11x+\frac{121}{4}=3+\frac{121}{4}

Now we will make a common denominator for right side.

x^2 +11x+\frac{121}{4}=\frac{12}{4}+\frac{121}{4}

x^2 +11x+\frac{121}{4}=\frac{133}{4}

Therefore, our equation would be x^2 +11x+\frac{121}{4}=\frac{133}{4}.

Write the expression as a single natural logarithm. 3ln3 + 3lnc
WARRIOR [948]
Using the rules of logarithms, you can change it to 

ln(3^{3}) + ln(c^{3}) = 

ln(27c^{3})

This is because when you have a factor in front of a logarithm, that turns into an exponent, and when you add logarithms, you multiply the factors inside of the logarithm.  

So your final answer is D.
