question 137

Multiple Choice

Simplify the complex fraction. $\frac { \frac { 2 x ^ { 2 } } { y ^ { 3 } } } { \frac { 4 x ^ { 4 } z ^ { 3 } } { y ^ { 5 } } }$ Assume that the denominators are not 0.

• A) \(\quad \frac { 1 } { 2 } x ^ { 2 } y ^ { 2 } z ^ { - 3 }\)
• B) \(\quad \frac { 1 } { 2 } x ^ { - 2 } y ^ { 3 } z ^ { - 3 }\)
• C) \(\quad \frac { 1 } { 2 } x ^ { - 2 } y ^ { 2 } z ^ { - 3 }\)
• D) \(\frac { 1 } { 2 } x ^ { 5 } y ^ { 4 } z ^ { 3 }\)
