False. EXPLANATION: A number is even if and only if it is an integer that ends in 0, 2, 4, 6, or 8. Integers that end in 1, 3, 5, 7, or 9 are odd. Since 888 ends in 8, it is even. 


Term
(T/F): 293 is an odd number. 

Definition
True. EXPLANATION: A number is even if and only if it is an integer that ends in 0, 2, 4, 6, or 8. Integers that end in 1, 3, 5, 7, or 9 are odd. Since 293 ends in 3, it is odd. 


Term
(T/F): The square root of 22 is a rational number. 

Definition
False. EXPLANATION: Only perfect squares have rational square roots. Since there is no integer that can be multiplied by itself to make 22, the square root of 22 is irrational. 


Term
(T/F): The square root of 22 is a rational number. 

Definition
False. EXPLANATION: Only perfect squares have rational square roots. Since there is no integer that can be multiplied by itself to make 22, the square root of 22 is irrational. 


Term
(T/F): The square root of 57 is a rational number. 

Definition
False. EXPLANATION: Only perfect squares have rational square roots. Since there is no integer that can be multiplied by itself to make 57, the square root of 57 is irrational. 


Term
(T/F): The square root of 81 is a rational number. 

Definition
True. EXPLANATION: The square root of 81 is 9, which is an integer, and therefore rational. 


Term
(T/F): The square root of 16 is a rational number. 

Definition
True. EXPLANATION: The square root of 16 is 4, which is an integer, and therefore rational. 


Term
(T/F): The square root of 64 is a rational number. 

Definition
True. EXPLANATION: The square root of 64 is 8, which is an integer, and therefore rational. 


Term
(T/F): The square root of 5 is an irrational number. 

Definition
True. EXPLANATION: Only perfect squares have rational square roots. Since there is no integer that can be multiplied by itself to make 5, the square root of 5 is irrational. 


Term
(T/F): The square root of 3 is an irrational number. 

Definition
True. EXPLANATION: Only perfect squares have rational square roots. Since there is no integer that can be multiplied by itself to make 3, the square root of 3 is irrational. 


Term
(T/F): The square root of 99 is an irrational number. 

Definition
True. EXPLANATION: Only perfect squares have rational square roots. Since there is no integer that can be multiplied by itself to make 99, the square root of 99 is irrational. 


Term
(T/F): The square root of 81 is an irrational number. 

Definition
False. EXPLANATION: The square root of 81 is 9, which is an integer, and therefore rational. 


Term
(T/F): The square root of 9 is an irrational number. 

Definition
False. EXPLANATION: The square root of 9 is 3, which is an integer, and therefore rational. 


Term
(T/F): The square root of 64 is an irrational number. 

Definition
False. EXPLANATION: The square root of 64 is 8, which is an integer, and therefore rational.
