Oh, dude, math time! So, like, 4 times 4 equals 16. It's a solid yes on that one. Unless you're talking about some new math I haven't heard of, but in regular math land, that's a definite 16.
4x4
16
8x2 DUH
4x4 = 16 is a perfect square.
Non-prime squares
1x16, 2x8, 4x4
1x16=16 2x8=16 4x4=16 sorry! all i know!
1x16=16 2x8=16 4x4=16 sorry! all i know!
1x16 2x8 4x4
It's not, 4x4=16.
4 times 4 does not equal 20, it equals 16. 5 times 6 equals 30.
