If you know your squares, you know that 82 is 64, 92 is 81, so we know that the square root is between 8 and 9. Using a calculatory device, we find it is ~8.94.
No, the square root of 6400 is 80, and 3200 squared is 10240000.
The positive square root of 80 is approximately 8.94. Since 8.94 is closest to 9, the number closest to the positive square root of 80 is 9.
√6400 = 80* * * * *OR -80
(Square root of 5) times 4
Just take the square root to find out what the sides are, then multiply it by 4, so 80^.5=8.94, 8.94*4=35.78
A negative number cannot have a square root in basic mathematics. However, in more advanced mathematics, you will study complex numbers. And there you will find that the square roots of -80 are ± 8.944*i where i is the imaginary square root of -1.Incidentally, ± 8.944 are the square roots of +80.
