What is log sub 5 of open paren 4 times 7 close paren plus the log base 5 of 2 written as a single log?

Use the product rule for logarithms: log₅(a) + log₅(b) = log₅(ab). First, 4 × 7 = 28, so the expression is log₅(28) + log₅(2) = log₅(28 × 2) = log₅(56). The correct choice is the log base 5 of 56.
