Question 1 • AZ-Common Core Algebra II A
A perfect cube can be written as a quantity raised to the third power. Since −1,000 = (−10)³, choice A is a perfect cube. Also, 27r²¹ = (3r⁷)³ and g³h³⁰ = (gh¹⁰)³, so B and D are perfect cubes. Finally, −1 = (−1)³; 343p is not generally a perfect cube because the exponent on p is 1.
