Expand the Logarithmic Expression log of square root of 100y

$\log (\sqrt{100 y})$

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{100 y}$ as ${(100 y)}^{\frac{1}{2}}$ .

$\log ({(100 y)}^{\frac{1}{2}})$

Expand $\log ({(100 y)}^{\frac{1}{2}})$ by moving $\frac{1}{2}$ outside the logarithm.

$\frac{1}{2} \log (100 y)$

Rewrite $\log (100 y)$ as $\log (100) + \log (y)$ .

$\frac{1}{2} (\log (100) + \log (y))$

Logarithm base $10$ of $100$ is $2$ .

$\frac{1}{2} (2 + \log (y))$

Apply the distributive property.

$\frac{1}{2} \cdot 2 + \frac{1}{2} \log (y)$

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{1}{2} \cdot 2 + \frac{1}{2} \log (y)$

Rewrite the expression.

$1 + \frac{1}{2} \log (y)$

Combine $\frac{1}{2}$ and $\log (y)$ .

$1 + \frac{\log (y)}{2}$
