In the exponential expression a raise to negative n is a positive integer the variable a cannot be equal to zero Explain why this is so?

a^(-n) = (1/a)^n
If a is 0, the above expression would require division by 0, which is not defined.

How do you know if an equation is exponential?
Basically, in an exponential expression (or equation) you have the independent variable in the exponent. For example: 5 times 10x The general form of an exponential function can be written as: abx or: aekx where a, b, and k are constants, and e is approximately 2.718. Note that just having a power doesn't mean you have an exponential equation. For example, in x3 the variable does NOT appear in the exponent, so it is not an exponential expression.
Can monomials have negative exponents?
Monomials can have negative exponents, if the term for the exponent is not a variable, but if it is a variable with a negative exponent, the whole expression will not be classified. This is so because the definition of a monomial states that, a monomial can be a product of a number and one or more variables with positive integer exponents. I hope that answered your question!
What is an equation that involves a number raised to a variable power?
An exponential equation.
What is the variable expression for negative ten decreased by 18 times a number?
-10-18x
What is a type of expression that contains a variable or variables?
An algebraic expression is a type of expression that contains a variable or variables.
Do all exponential functions show growth over time?
If the exponent has the variable of time in it, then it will be either exponential growth (such as compound interest for example), or exponential decay (such as radioactive materials, or a capacitor discharging). If the time constant (coefficient of the time variable) is positive then it is growth, if the time constant is negative, then it is decay.
In math what does an exponential expression mean?
It means that the variable of interest appears as a power in the expression. So, for example, 3x is exponential but x3 is merely cubic. The distinction depends on the position of x.

Will the answer by negative if you are dividing by a negative variable?
If you are dividing a positive by a negative, yes. If you are dividing a negative by a negative, you will get a positive.

Which term describes a fraction that has a variable or variable expression in its numeratordenominatoror both?
There is no specific name. They can be fractions which contain algebraic or trigonometric or non-integral exponential expressions.
Decide whether the following equation is exponential. Support your answer -3x 4y plus 7 and sup2.?
While this is not the complete definition, an exponential expression has the variable (for example, "x") in the exponent.
What is an equation that involves a number raised to a variable power?
An exponential equation.
Can there be a negative float?
A float variable can store both positive and negative numbers.
If you replace a negative variable with a negative number does the number become positive?
Yes
Is 4d a numerical expression or variable expression?
A variable expression.
When is an algebraic expression considered as a non-polynomial expression?
An expression is non polynomial if it has : negative exponent fractional exponent variable exponent in the radicand
