Exponent - the number usually a superscript, indicating the number of times a number is multiplied to itself.

Square Root - the square root of x is a number y such that y^2 = x
Only Positive Numbers have Real number square roots
Negative Numbers have imaginary square roots
A positive number has two square roots, one POSITIVE and one NEGATIVE

-> means negative square root
Example

Some number do not have whole number square roots, some numbers have radicals as square roots
