No.
a^(-n) = (1/a)^nIf a is 0, the above expression would require division by 0, which is not defined.
A typical formula for exponential decay is y(t) = c*exp(-r*t) , where r > 0. The domain is all reals, and the range is all positive reals, since a positive-base exponential always returns a positive value.
Domain of the logarithm function is the positive real numbers. Domain of exponential function is the real numbers.
The exponential expression a^n is read a to the nth power. In this expression, a is the base and n is the exponent. The number represented by a^n is called the nth power of a.When n is a positive integer, you can interpret a^n as a^n = a x a x ... x a (n factors).
No.
multiterm mathematical expression: a mathematical expression consisting of the sum of a number of terms, each of which contains a constant and variables raised to a positive integral power
* If "a" is positive, "-a" is negative.* If "a" is negative, "-a" is positive. * If "a" is zero, "-a" is zero. If you want to force a negative number, you can write -|a|, i.e., the negative of the absolute value.
a^(-n) = (1/a)^nIf a is 0, the above expression would require division by 0, which is not defined.
Yes.

both, variables can be anything
One to any power is still one. If the power is positive, you have 1 times itself over and over again, so it does not change. If the power is zero, the answer is always one, no matter the number. If the power is negative, you find the reciprocal of the expression and make the power positive. If the base of the exponential expression is 1, it is always one.
All positive integers have an exponential form. For example, 43 can also be written as 431.
A typical formula for exponential decay is y(t) = c*exp(-r*t) , where r > 0. The domain is all reals, and the range is all positive reals, since a positive-base exponential always returns a positive value.
Positive correlation is a relationship between two variables in which both variables move in tandem that is in the same direction.
Domain of the logarithm function is the positive real numbers. Domain of exponential function is the real numbers.
