4X16 is equal to 8X8 because:
Let 4 represent x.
16x = 2x(8)
16x = 16x.
Both sides of the equation are equal, so therefore 4 times 16 and 8 times 8 are equal.
You get 2x(8) by realizing that 8 is 4 times 2. Since we are using x in place of 4, rather than saying "4 times 2" we simply say 2x.
In order to finish the statement, 8 times 8, you take the 2x and multiply it by 8. So you have:
2x(8)
The same is for "4 times 16"
In place of 4 you use x, thus making it 16x.
After simplifying the equation it comes out to 16x = 16x, proving that it is equal.

2x2 2x8 4x16= 64
2 and 1/4
9x7 and 7x9 are the same and equals to 63 whereas 8x8 equals to 64 so therefore 8x8 is greater than both 9x7 and 7x9.
a easy way 2 remember 8x8 is: i ate and i ate till i sick on the floor 8x8 is 64 or i ate and i ate till i was 64 8x8 is 64 and sorry for the first one lol silly me
