Expand the logarithm:  $\log\ \frac{x^3}{zy^4}$  

• log(x) + log(z) + 4log(y)

• 3log(x) − log(z) − 4log(y)

• 3log(x) + log(z) + 4log(y)

• log(x) − 4log(z) − 3log(y)

Condense the logarithms:  $5\log a-25\ \log b$  

• log (a⁵ + b²⁵)

• log (a⁵ − b²⁵)

• log (ab²⁵)

• log (a⁵/b²⁵)

Condense the logarithms:  $2\log_5z\ +2\log_5x+10\log_5y$
