The steps for solving negative exponents are simple.

How to solve with negative exponents. How does a negative exponent affect our answer. First you write your base number down as its reciprocal. X a 1 x a Examples of rewriting negative examples as positive 1 5 2 1 5 2 2 3 x 2 1 3 x 2.

Flip the base and exponent into the reciprocal then solve the denominator. Warns against confusing minus signs on numbers and minus signs in exponents. Demonstrates how to simplify fractions containing negative exponents.

That last example showed an easier way to handle negative exponents. The procedure to use the negative exponents calculator is as follows. Check out my video above for the complete step-by-step process on solving for negative exponents.

1 5 5 5 153 1125 0008. Now you can move on to exponents using the cancellation-of-minus-signs property of multiplication. Finally you solve as you would a positive exponent.

Dont be scared by the fact that the exponent is negative. Perhaps youd like to try solving some equations with negative exponents on variables. Negative Exponent Rule 1.

A negative exponent just means that the base is on the wrong side of the fraction line so you need to flip the base to the other side. For instance 3 2 33 9So we can use some of what weve learned already about multiplication with negatives in particular we weve learned about cancelling off pairs of minus signs when we find negative numbers inside. Divide the numerator by the denominator to find the final decimal.

Provides worked examples showing how the same exercise can be correctly worked in more than one way. Negative exponents can be very tricky if you dont know how to solve them. Just work it out and remember to flip over invert the number if it has a negative exponent.

5-3 could also be calculated like. If that sounds confusing there is no need to worry as it will all be explained later on in t. Now click the button Solve to get the result.

For instance x2 pronounced as ecks to the minus two just means x2 but underneath as in frac 1 x2 x21. For example 4 -3 Here the base number is 4 and the exponent is -3. Finally the value of the given exponent will be displayed in the output field.

To convert a negative exponent create a fraction with the number 1 as the numerator top number and the base number as the denominator bottom number. Recall that powers create repeated multiplication. The general formula for rewriting negative exponents as a positive exponent is.

How to solve negative exponents Most questions will ask you to solve negative exponents by expressing them as positive equations. Basically you need to start dividing 1 by your base once you get to negatives. Before you assume that the answer must be negative think againPractice this lesson yourself on KhanAcademy.

Next the exponent changes from positive to negative. 5-3 1 5 5 5 0008. Raise the base number to the power of the same exponent.

For every number a with negative exponents -n ie a -n take the reciprocal of the base number and multiply the value according to the value of the exponent number. Learn how to solve negative exponents in these step by step examples. A negative exponent means how many times to divide by the number.

But that can be done an easier way. 8-1 1 8 18 0125.
