Basically do the same thing you would with a positive exponent. However, the difference with negatives is that it will be a fraction with 1 over whatever the exponent comes out to. The negative just tells you to flip the position of the exponent from the numerator to the denominator.

For example if you have 5-2, it would become 1/52, which would then become 1/25.

Also, if you have a negative exponent in your denominator, you would flip it up to the numerator.

For example if you have 1/5-2, it would become 52, which would then be 25.

How do you raise anumber to a negative exponent?

A number to a negative exponent is the inverse of the number to the positive exponent. That is, x-a = 1/xa

Why is a number to a negative exponent a fraction?

Because a number to the exponent 0 = 1 and any lesser exponent decreases the value.

What is the negative exponent law?

If you have a negative exponent, then put 1/the number multiplied by itself the number of times of the exponent. For example: 3-2=1/(3x3)=1/9

What are the rules for a number with a negative exponent?

A number with a negative exponent should be treated as the reciprocal of that same number with the analogous positive exponent. For example, 42 = 16, but 4-2 = 1/42 = 1/16.

What happens if your number has a negative exponent?

That number becomes an exponent. For example, 5 to the -2 power is 1/25

What does it mean when an exponent is a negative number?

A negative exponent is the reciprocal of the corresponding positive exponent. 102 = 100 10-2 = 1/100

What do you do when you have a negative number to a negative exponent?

it would be a negative multiplied by a negative and your answer should end up positive.

How do you solve a positive number with a negative exponent?

turn the positive number into its recipricol and the put the number of the negative number on the top

When is the exponent negative?

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

What happens to a negative number with a positive exponent?

It will become a positive number.

When squaring a negative number if the factor is a negative and the exponent is positive will your answer be negative or positive?

If you square any real number it will always be positive.

Where is the negative exponent key on a calculator?

When will the exponent be negative in scientific notation form?

The exponent will be negative when the absolute value of the number is between 0 and 1. For example, 1X10-1 is 0.1.

What does the term negative exponent mean in math?

the exponent is a negative

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 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.

When a number written in scientific notation includes a negative exponent is the number negative?

No, if there is a negative number then you put that many numbers before the root number. For example, 7x10^-5= .000007

Can a polynomial have a negative exponent?

Polynomials cannot have negative exponent.

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.

Is a number that can be expressed using an exponent?

Every number can be expressed using an exponent. You select a base, b, which should be a positive real number. Suppose the number is x.If this number is negative, then its exponent form will have a negative sign before it.The absolute value of the number is converted to the exponent form by solving x = b^y where y is the exponent. However, you need to know about logarithms before you can do that (and this question suggests that you have not yet progressed to that level of mathematics).

What is negative exponent?

It's a number up and just to the right of the bigger first number. If its. 3 2 Then you multiply it like 2 times 2times 2 With negative exponent you switch it from negative to positive every other one starting with negative. We do this because a negative and a negative multiplied together equal a positive and a positive times a negative is negative. -123771

How do you change negative exponets to positive exponents?

A negative exponent of a number is the same as the reciprocal of that same number to the equivalent positive exponent.EXAMPLE : 2-3 = 1/23When multiplying powers of the same base the rule is, addthe exponents.So, if the initial exponent is negative then the number has to be multiplied by a power of that number with an equivalent positive exponent greater than the negative exponent.EXAMPLE : 2-3 x 25 = 2(-3+5) = 22 (As 5 > l3l then the resultant exponent is positive)

Is a exponent a number with a plus or - sign?

You fail SO badly. If we have x^4, the 4 is the exponent- the power to which a number is raised. It can be positive or negative.

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 write a decimal using a negative exponent?

When you have a negative exponent (for example 3^-3) you could make the recipricol of the number. So, this would be 1/3^3. Then all that you would have to do is solve for the exponent ( so in this case the answer would be 1/27)
