It can be either.
Why not? An exponent is just like any other number.
10-6 = (1/10)6 = 0.000 001
Flip the fraction top-to-bottom, and delete the minus sign from the exponent.
Yes.
A negative exponent is put into fraction form because it is a way of writing powers of fractions or decimals.

Yes.
The reciprocal of a^(-x/y) is 1/a^(x/y). The fact that the exponent is a fraction makes no difference.
A fraction
a decimal fraction means a fraction that changes into a decimal or a decimal that changes into a farction
decimal point exponent
A negative exponent is put into fraction form because it is a way of writing powers of fractions or decimals.
Because a number to the exponent 0 = 1 and any lesser exponent decreases the value.
The exponent tells you how many spaces to move the decimal, remember to add zeros as needed. If the exponent is negative make it a decimal number less than one by moving the decimal to the left. If the exponent is positive make the decimal number greater than one by moving the decimal to the right.
See the related link about Standard Form. Standard form involves moving the decimal point so that there is only one non-zero digit to the left of the decimal point, then multiplying by an appropriate power of ten. If you moved the decimal point to the left, then the exponent of ten will be positive. If you moved the decimal point to the right, then the exponent of ten will be negative. The value of the exponent is equal to the number of places that the decimal is moved.Example:105 = 1.05 x 102 (the decimal was moved 2 places to the left).00356 = 3.56 x 10-3 (the decimal was moved 3 places to the right)
