Question 8 • Algebra 2 with Probability

Which expression is equivalent to 5th root of 32 x to the 5th power y to the 10th power z to the 15th power ?

Answer
A
2 x y squared z cubed
B
2 y to the 5th power z to the 10th power
C
6 y to the 5th power z to the 10th power
D
6 x y squared z cubed

Explanation

Take the fifth root of each factor: the fifth root of 32 is 2, and the fifth roots of x⁵, y¹⁰, and z¹⁵ are x, y², and z³. Therefore, the expression simplifies to 2xy²z³, which is choice A.
