ANSWER


log(5(4 * 7)) + log( {5}^(2) ) = log(3500)

EXPLANATION

We want to write the following as a single logarithm.




log(5(4 * 7)) + log( {5}^(2) )

We apply the following property of logarithms.



log(a) + log(b) = log(ab)

This implies that,



log(5(4 * 7)) + log( {5}^(2) ) = log(5 * 4 * 7 * {5}^(2) )




We simplify to get,




log(5(4 * 7)) + log( {5}^(2) ) = log(3500)
