Question

Would you classify 121 as a perfect square, perfect cube, both, or neither?Choose the correct answer below.O A. The number is a perfect square because = 121.OB. The number is a perfect cube because= 121OC. The number is both a perfect square and a perfect cube because= 121 and= 121OD. The number is neither a perfect square nor a perfect cube because there is no integer thatcan be squared to get 121 and no integer that can be cubed to get 121.

Answer 1

To know if a number is a perfect sqare of a perfect cube you:

perfect sqare

determine if its sqaure root is an integer. If is not an interger, then the number is not a perfect sqare

$\sqrt[]{121}=11$

perfect cube

determine if its Cube root is an interger. If is not an interger then the number is not a perfect cube

$\sqrt[3]{121}=4.94$

Then so, 121 is a perfect cube, because is the result of (11*11)

121 is not a perfect cube
