It ends in 0 or 5.
720.
It is zero
How about: 20 and -2
-11 x 12 = -132
The product of two rational numbers is always a rational number.
The product of its prime factors which are: 3*13 = 39
Square root of 4 is 2 and so 2 times 16 = 32
The answer is 8 and 5!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
{5, 5, 8, 8, 12}{5, 5, 8, 8, 12}{5, 5, 8, 8, 12}{5, 5, 8, 8, 12}
5/8 ÷ -1 = -5/8
Added: 4.5 ± 12.6392 i where i is the imaginary square root of -1
