Raise to the Power or Find the Root (9z8/3x2/3y7/3)1/2\left( \frac { 9 z ^ { 8 / 3 } } { x ^ { - 2 / 3 } y ^ { 7 / 3 } } \right) ^ { 1 / 2 }

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.
- (9z8/3x2/3y7/3) 1/2\left( \frac { 9 z ^ { 8 / 3 } } { x ^ { - 2 / 3 } y ^ { 7 / 3 } } \right) ^ { 1 / 2 }


A) 9z4/3x1/3y7/6\frac { 9 z ^ { 4 / 3 } } { x ^ { 1 / 3 } y ^ { 7 / 6 } }
B) 3z4/3x1/3y7/6\frac { 3 z ^ { 4 / 3 } x ^ { 1 / 3 } } { y ^ { 7 / 6 } }
C) 3x2/3y7/6\frac { 3 x ^ { 2 / 3 } } { y ^ { 7 / 6 } }
D) 3z4/7x1/6y7/6\frac { 3 z ^ { 4 / 7 } x ^ { 1 / 6 } } { y ^ { 7 / 6 } }
