Answer: 1. (Option C.) Quotient property: loga(bc) = loga(b) + loga(c)
2. (Option B.) Change of base rule: logb(c) = loga(c) / loga(b)
Explanation:
Using the quotient property, you can simplify log57 + log74 as follows:
log57 + log74 = log(57 * 74) = log(4198)
Alternatively, you could use the change of base rule to convert the logarithms to the same base, then use the quotient property to simplify the expression.
Hope this helps.
