Final answer:
To expand the given logarithm expression using properties of logs, multiply the exponents by the logarithms of the variables and simplify the expression.
Step-by-step explanation:
To expand the expression logx3 * logy4 fully using the properties of logs, we can apply the property that the logarithm of a product is the sum of the logarithms of the individual factors. Therefore, we can rewrite the expression as (3 * logx) + (4 * logy).
This expansion gives us a simplified expression that represents the given logarithm.
