easy, lets take radical negative 3 for example. you can take out a "i" because i = the radical negative one. There fore the answer is i radical 3.
Where do we see negative numbers
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
It belongs to the set of negative rational numbers, negative real numbers, fractionall numbers, rational numbers, real numbers.
No, not all negative numbers are rational. There are many negative numbers that are irrational, just like the positive numbers.

So you don't have to write out an incredible amount of zeroes. Imagine having to write 1x10 to the thousand in normal numbers. It's much easier to use standard form.
Write the mantissa as a negative number.

0.000001, 1x10-6 or 1/1000000
It is: 1.25*10^-7
