An exponent is the power that a number is raised to. For instance, in the expression 3^2 ("three squared"), 2 is the "exponent" and 3 is the "base." A positive exponent just means that the power is a positive number. For instance, the following expression does not involve a positive exponent: 3^(-2). Horses rule!!!!!
A negative exponent is the reciprocal of the corresponding positive exponent. 102 = 100 10-2 = 1/100
This is a procedure used to help people who are new to negative exponents. A negative exponent, when moved to the other side of the fraction, becomes a positive exponent and beginners are more comfortable with working with positive fractions.
An expression with a negative exponent is equivalent to the positive exponent of its reciprocal. Thus, 3-4 = 1/34 or, equivalently, (1/3)4 or (3/4)-2 = (4/3)2
"Dose" is a measured portion of a medicine. I am not aware of any exponents that have anything to do with measured quantities of medication! A negative exponent is simply the reciprocal of the corresponding positive exponent. Thus x^(-a) = (1/x)^a for non-zero x.

An exponent that is a positive integer. For example, x3 has a positive exponent, while 8-5 does not.
When the number is very large 1.0 x 10^6 is 1 million.
You evaluate the powers of 10 and a exponent of positive 4.
An exponent that is a positive integer. For example, x3 has a positive exponent, while 8-5 does not.
To predict whether a power will be negative or positive, examine the base and the exponent. If the base is positive, any exponent—whether positive or negative—will yield a positive result. Conversely, if the base is negative, an even exponent results in a positive value, while an odd exponent produces a negative value. Thus, the sign of the power depends on both the sign of the base and whether the exponent is odd or even.
No.
A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa
Say it with a lot of sarcasm.
To change a negative exponent to a positive one, you take the reciprocal of the base raised to the positive exponent. For example, ( a^{-n} ) can be rewritten as ( \frac{1}{a^n} ), where ( a ) is the base and ( n ) is the positive exponent. This rule applies to any non-zero base.
It will become a positive number.
(4x^-4)^-2 = ?
Yes.
