think about it this way... a negative times a negative is a positive... squaring is the same as multiplying it by itself. 4^2 is 16, 4X4 is 16. -7X-7 is positive 49. So a square can't be negative, therefore a negative cannot be square rooted.

This can never be. The square of any number will always be positive. Any positive number multiplied by another positive number will be positive, while any negative number multiplied by another negative number will be positive.
The first square number is 4 while the first cubic number is 8. Condition: you do not consider 1 as an answer since 1x is surely 1 for any value of x, from negative to infinite.
negative multiply by negative is positive. While negative added with negative is negative. E.g. - 2 x -2 is 4 while -2 + -2 is -4
That is any number that is an integer, and the square of another integer. For example, 4 is the square of 2, while 9 is the square of 3.That is any number that is an integer, and the square of another integer.

In simple terms, negative numbers don't have square roots. If you multiply a number by itself, you can never get a negative number for the answer. Square a negative or a positive, you get a positive; square zero, you get zero.Now, if you get fancy, you could say that while a negative number has no real square roots, you can make one up by inventing the imaginary number i, which is the number that when squared, equals -1. Then you can say that sqrt (-96) = [ sqrt(-1) ] * [ (sqrt(96) ] = i*sqrt(96). From here, you can go ahead and simplify sqrt(96) ...Look for a perfect square factor, and take it out of the root: 96 = 4x24 = 4x4x6 = 16x6; sqrt(96) = sqrt(16)*sqrt(6) = 4sqrt(6).So sqrt(-96) = i*4sqrt(6), which is customarily written as 4isqrt6(You would write a radical sign wherever it says "sqrt" above.)
