<em>Write any 4 laws, or properties, of exponents.</em>
<em />
<em> </em>



When we multiply together numbers with the same base,
we add the exponents.



When we divide numbers with the same base, we
subtract the exponents.



If we have a fraction to a power, we raise the numerator and
the denominator to that power.
And then last but not least,



If we have a number with a negative exponent, we flip it over.

Two numbers that add up to -19 and multiply to 48 are -16 and -3:

So, the solutions come from each parentheses: x+4=0, x-4=0, and x^2-3=0.
x+4=0
x = -4
x-4=0
x = 4
x^2-3=0
x^2 = 3
x = +/- √3
So, the solutions are -4, -√3, √3, and 4.
