How to divide fractions with negative exponents. This algebra math video tutorial focuses on simplifying exponents with fractions variables and negative exponents including examples involving multiplicati. With negative exponents are moved to the bottom of the fraction. First convert the negative exponents to positive exponents by taking the reciprocal of the given number.
Thus ⅔ -2 becomes 32 2 and 42 -3 becomes 24 3 Now multiply the numbers we get. The negative power will become just 1 once I move the base to the other side of the fraction line. Since d -3 on the bottom has a negative exponent it is moved to the top of the fraction numerator.
Sometimes the smaller number will be in the numerator and you will end up with a. So if you have 3-4 in the numerator of a fraction. This algebra math video tutorial explains how to simplify negative exponents in fractions with variables and parentheses.
Anything to the power 1 is just itself so Ill be able to drop this power once Ive moved the base. Divide expressions with negative exponents. The multiplication of two numbers with negative exponents such as ⅔ -2 and 42 -3 is as follows.

To divide expressions with negative exponents all you have to do is move the base to the other side of the fraction line. If theres nothing in common go directly to solving the equation. 2x -1 dfrac 2x -1 1 2x1 12x1.
It discusses the basic properties. Simplifying Exponents With Fractions Variables Negative Exponents Multiplication Division MathThis algebra math video tutorial focuses on simplifying e. The negative sign on an exponent means the reciprocal.
The answer is 116. Just as a positive exponent means repeated multiplication by the base a negative exponent means repeated division by the base. The top and bottom both contain negative exponents.
Remember to flip the exponent and make it positive if needed. Dividing negative exponents Dividing negative exponents is almost the same as multiplying them except youre doing the opposite. If the bases are the same subtract the exponents.
Remember to flip the exponent and make it positive if needed. The next problem is already a fraction. So 2 -4 1 24 1 2222 116.
If the bases are the same subtract the exponents. Raise the base number to the. Click to see full answer.
For problems like these the exponent in the denominator is always subtracted from the exponent in the numerator. Think of it this way. Dividing by a negative exponent is equivalent to multiplying by the same positive exponent so you can rewrite this expression.
If the exponents are the same but the bases are different divide the bases first. 2 1 x 1 2 x.
