Keep in mind that, when the logarithm base is not explicitly written, base 10 is assumed, therefore,

$\bf \textit{Logarithm Cancellation Rules}\\\\
log_a a^x\implies x\qquad \qquad a^{log_ax}=x\\\\
-------------------------------\\\\
10^{log(3)}+log(100)\implies 10^{log_{10}(3)}+log_{10}(100)\implies 3+log_{10}(10^2)
\\\\\\
3+2\implies 5$

sammy [17]

Answer:

You need 3 cups of brown sugar for every 1 cup of white sugar.

Step-by-step explanation:

To find the smallest amount possible, divide both numbers by the smaller number. So, 6 (the amount of brown sugar) Divided by 2 equals 3, and 2 (the amount of white sugar) Divided by 2 equals 1.
