An important rule of logs is a*log b = log b^a.

Thus, 2 (log to the base 5 of )(5x^3) = (log to the base 5 of ) (5x^3)^2, or

(log to the base 5 of ) (25x^6).

Next, (1/3) (log to the base 5 of ) (x^2+6) = (log to the base 5 of ) (x^2+6)^(1/3).

Here, the addition in the middle of the given expression indicates multiplication:

2Log5(5x^3)+1/3log5(x^2+6) = (log to the base 5 of ) { (5x^3)^2 * (x^2+6)^(1/3) }.

Here we've expressed the given log quantity as a single log.

The amount of blue color in the green paint is an illustration of ratios and proportions.

Cheryl's green paint has more blue color

The proportion of blue color is calculated as:

\mathbf{Proportion = \frac{Blue}{Blue+ Yellow}}

So, we have:

\mathbf{Cheryl= \frac{16}{16+ 24}}

\mathbf{Cheryl= \frac{16}{40}}

\mathbf{Cheryl= 0.40}

Express as percentage

\mathbf{Cheryl= 40\%}

\mathbf{Rodney= \frac{6}{6+ 10}}

\mathbf{Rodney= \frac{6}{16}}

\mathbf{Rodney= 0.375}

Express as percentage

\mathbf{Rodney= 37.5\%}

By comparison: 40% >37.5%

Hence, Cheryl's green paint has more blue color
