Standard rules for exponents....

1 the square root of any number has an exponent of .5

2 any number raised to the zero power equals 1

3 any number raised the the exponent of n, means the that number gets multiplipied by itself as many times as the value of the exponent.

4 any negative exponent means - first figure out what the value should be if it were not negative....then take 1 and divide by that positive evaluation.


some examples

2 exponent 3.5 = ( 2 x 2 x 2 x the square root of 2 )

3 exponent -1.5 = 3 x the square root of 3 x pi x pi )

pi exponent -2 = 1 / ( pi x pi )


To better compare these results to one another, it is part of this scheme to...
Take that decimal result is then converted to its significant digits.
All decimals values are seen as being from 1.00000000... to 9.99999999.... x 10 to the n.
