question 260

Multiple Choice

Raise to the power or find the root. Assume that all variables represent positive real numbers. Write with only positive
exponents.

• B) \(\frac { 3 z ^ { 4 / 3 } x ^ { 1 / 3 } } { y ^ { 7 / 6 } }\)
• C) \(\frac { 3 x ^ { 2 / 3 } } { y ^ { 7 / 6 } }\)
• D) \(\frac { 3 z ^ { 4 / 7 } x ^ { 1 / 6 } } { y ^ { 7 / 6 } }\)
