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 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).

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.

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)
