It certainly has a meaning. It is only meaningless if you consider powers as repeated multiplication; but the "extended" definition, for negative and fractional exponents, makes a lot of sense, and it is regularly used in math and science.

When is the exponent negative?

When you subtract it from a bigger exponent of another number by dividing two numbers with exponents.


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!


Numbers that are in scientific notation that have a negative exponent are?

Exponents are negative numbers. This is used in math a lot.


How do you get rid of negative exponents?

Negative exponents indicate that the number for which the exponent applies to should be placed under one. Ex: 2^(-3) also can be expressed as 1/(2^3) or 1/8. So, to eliminate the negative exponent, simply place the number (and the accompanying exponent) under one to make a fraction.


What is the difference between scientific notation and negative exponents?

Scientific notation is a way to express very large or very small numbers. For very large exponent is positive; for very small exponent is negative. For example, 1,000,000 is 1 x 10 to the plus 6 exponent; 0.000001 is 1 x 10 to the negative 6 exponent


How do you make a decimal into a negative exponent?

You look at the denominator first. Then you try to find out what exponents make the denominator. After doing that, you add a negative symbol to the smaller number on the exponent.


What are negative intergery exponents?

I assume you mean "negative integer exponents".It means that: * It is an exponent * It is an integer (whole number) * It is negative (less than zero, i.e., with a minus sign) A negative exponent is defined as the reciprocal of the positive exponent. For example, 10 to the power -5 is the same as 1 / (10 to the power 5).


How do you express negative exponents as positive exponents while multiplying?

you make it into a fraction by puting whatever the negative exponent is attach to an pu that on the botttom of the fraction and leave a one on top


Why do you move a negative exponent to the other side of the fraction?

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.


When is an exponent positive?

When it is anything above zero. Negative exponents are below zero and zero is nuetral.


How do you simplify negative numbers with positive exponents?

If the exponent is an even number you can drop the negative, because is you were to multiply it out the negatives would cancel out.


Is a negative number with a negative exponents positive?

If the exponent is an even number, then yes, because exponents are basically repeated division and negatives always cancel each other out in division. However if the exponent is an odd number, the number will remain negative, because they can't form even pairs to cancel one another out.


How do you change negative exponents to positive exponents?

If you have 10^-3 then you can consider it the same as (1/10^3) and you have changed the negative exponent to positive exponent. Similarly, if the original number is (1/10^-3), that is equivalent to 10^3. In most cases it is as simple as taking the reciprocal.


How will you simplify expressions with negative exponents to get positive exponents?

A negative exponent becomes positive in the reciprocal. So if you have a number a^x where x is negative, then, a^x = 1/(a^-x) and, since x is negative, -x is positive.


What is Five to the power -1?

Negative exponents are the reciprocal of the base to the positive exponent.1/5 is the answer.


What do Negative exponents indicate?

Raising a number to a negative exponent gives you the reciprocal of the same number raised to the corresponding positive exponent. For example, 32 = 9, so 3-2 = 1/9


How do you solve negative integral exponents?

A negative exponent is simply the reciprocal of the positive exponent. So simply remove the negative sign and find the reciprocal. Thus, for example, 5-3 = 1/53 = 1/125


How could negative exponents create a zero exponent?

Because negative exponents doesn't exist in our world. And thus, can only be explained with 0. Hope that answered you question. *WIDE SMILEY FACE!*


What does the exponent or power mean in math?

An integer exponent is the number of times that a number is multiplied by itself. For example: if the exponent of a is 3, then it represents the number a3 = a*a*a. The laws of exponents can be extended to arrive at definitions of negative exponents [a-3 = 1/a3] and fractional exponents [a1/3 is the cube or third root of a]. These definitions can be further extended to exponents that are irrational numbers, or even complex number.


How do negative exponents become positive?

when an exponent is shifted from the left side of equal to to right side or visa verse


What is negative exponents?

A negative exponent is simply the reciprocal of the positive equivalent. For example 3-2 = 1/32 = 1/9


What are negative exponents?

Exactly that ... negative exponents. For example: 1000 = 103 That is a positive exponent. .001 = 10-3 That is a negative exponent. For positive exponents, you move the decimal place that many positions to the right, adding zeros as needed. For negative exponents, you move the decimal place that many positions to the LEFT, adding zeros as needed. And, the special case is this: 100 = 1.
