if not explain why and simple cuz im only in 5th grade
no, 11 times 11 is 121
so its a perfect square
11 x 11 = 121 so 121 IS NOT prime.
11 is a factor of 121
121 can be divided by 11.
A prime number can ONLY be divided by itself and 1.
Some prime numbers are 2 , 3 , 5 , 7 , 11 , 13 , 17, 19 , 23 , 29--------
No,because 121 = 11^2 (11 x 11)
No. It has a factor of 11. 11*11=121.
121 is a square number.
no, it can be divided by 11. A prime number means it can only be divided by 1 while 121 is not

RE:
Is 121 a prime number?
No, because 121 = 11 x 11. If it was prime, you wouldn't be able to write it as two numbers multiplied together. For example, 17 is prime because you can't write it as two numbers multiplied together.
no, it is divisble by 1, 11, 121
nope 'cause a prime number is one which can only divide by itself and 1, like 2(divided by 1 =2 and divided by 2=1, can't be divided by anything else)
121 can be divided by 11=11 so it is not a prime number, hope it helps:D
composite = having other factors other than 1 and itself 11*11 is 121 so its factors r 1, 11, 121 therefore, it's composite
