When dealing with fractions, you may come across negative exponents. These exponents play a crucial role in mathematical operations and need to be understood to solve problems accurately. In this article, we will guide you step-by-step on how to calculate a fraction with a negative exponent.

Step 1: Rewrite the Fraction

The first step is to rewrite the fraction using positive exponents. We can achieve this by applying a simple mathematical operation. Let’s take the example of a fraction: 1/2-3. To rewrite this fraction, we move it to the denominator and change the sign of the exponent. The new fraction will be: 1/23.

Step 2: Evaluate the Positive Exponent

Now that we have rewritten the fraction with a positive exponent, we can proceed to evaluate it. In this step, we need to calculate the value of the denominator. Using the example from Step 1, 2 raised to the power of 3 equals 2 × 2 × 2, which equals 8. Therefore, the new fraction becomes: 1/8.

Step 3: Simplify the Fraction (if needed)

If the fraction obtained in Step 2 can be simplified further, it is advisable to do so. Simplifying fractions provides a more concise and straightforward form, making it easier to work with. However, not all fractions can be simplified any further. In our case, the fraction 1/8 cannot be simplified any further, so we leave it as it is.

Step 4: Final Result

After following the above steps, we have successfully calculated the fraction with a negative exponent. The final result for our example is 1/8. Remember to check if your answer matches the requirements of the problem you are solving or if it needs to be further manipulated.

Calculating fractions with negative exponents is a fundamental skill in mathematics. By following the steps outlined in this article, you can confidently convert a fraction with a negative exponent into a simplified form. Understanding and mastering this technique will enhance your problem-solving abilities and strengthen your overall mathematical skills.
