Divide the numerator by the denominator to find the final decimal.

How do you solve for a negative exponent. Before you assume that the answer must be negative think againPractice this lesson yourself on KhanAcademy. Finally the value of the given exponent will be displayed in the output field. Without parentheses the exponent is applied before the negative sign.

The best way to remember how to deal with a negative exponent is to remember that negative is the opposite of positive and division is the opposite of multiplication so a number with a negative exponent should be moved to the denominator of a fraction and the exponent switched to positive. Perhaps youd like to try solving some equations with negative exponents on variables. However if the negative number is in parentheses then the exponent is applied to the entire negative number.

Calculate the positive exponent an Then take the Reciprocal ie. In this lesson you will learn about the negative exponent rule negative exponent definition multiplying negative exponents and how to work with negative. This page includes a lesson covering how to convert scientific notation with a negative exponent to a number as well as a 15-question worksheet which is printable editable and sendable.

This works just like solving any other equation. How to solve negative exponents Most questions will ask you to solve negative exponents by expressing them as positive equations. Suppose a negative exponent is given to you for example 8 -1 you can easily solve it by taking it as 18.

It is for students from Year 7 who are preparing for GCSE. That last example showed an easier way to handle negative exponents. 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.

If instead you would have been given a value 10 -1 it would have resulted as 110. Just work it out and remember to flip over invert the number if it has a negative exponent. Ill show both ways.

1an To change the sign plus to. Enter the base and exponent value in the respective input field. In the expression -32 32 is calculated to give 33 9 then the negative sign is attached to give a.

This is a KS3 lesson on converting scientific notation with a negative exponent to a number. 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. The general formula for rewriting negative exponents as a positive exponent is.

Negative Exponent Rule This is nothing more than moving the base of our exponential expression from the top to the bottom or vise-versa and changing the exponent from negative to. The opposite is also true. For instance x2 pronounced as ecks to the minus two just means x2 but underneath as in frac 1 x2 x21.

Dont be scared by the fact that the exponent is negative. The procedure to use the negative exponents calculator is as follows. Again I can work either of two ways.

How does a negative exponent affect our answer. Now click the button Solve to get the result. The best way to remember how to deal with a negative exponent is to remember that negative is the opposite of positive and division is the opposite of multiplication so a number with a negative exponent should be moved to the denominator of a fraction and the exponent switched to positive.

Multiply first and then handle the negative exponents or else handle the exponents and then multiply the resulting fractions.
