How do you solve a fraction with a negative exponent in the denominator?

A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa. For example, when you see x^-3, it actually stands for 1/x^3.

What if there is a negative in the denominator?

Where does the negative sign go in a fraction? If both the numerator and denominator are negative, then the fraction itself is positive because we are dividing a negative by a negative.

A negative exponent shows that the decimal point is shifted that number of places to the left. In scientific notation, the digit term indicates the number of significant figures in the number. As another example, 0.00053 = 5.3 x 10-4 This number has 2 significant figures.

Can you have a negative exponent in a polynomial?

A polynomial cannot have a variable in the denominator or a negative exponent, since monomials must have only whole number exponents.

How do you add a negative exponent?

First, redistribute the power to the inside of the brackets, following the third exponent rule. Then, flip the 𝑥 variables with negative exponents to their reciprocal. Finally, multiply the 𝑥 variables by adding the exponents together.

How do you find negative fractions?

If you have negative fractions insert a minus sign before the numerator. So if one of your fractions is -6/7, insert -6 in the numerator and 7 in the denominator. Sometimes math problems include the word “of,” as in What is 1/3 of 3/8? Of means you should multiply so you need to solve 1/3 × 3/8.

How do you multiply numbers with negative exponents?

When you have negative exponents, the negative exponent rule dictates that, instead of multiplying the base the indicated number of times, you divide the base into 1 that number of times. So 8 -2 = 1/(8 • 8) = 1/16 and 10-3 = 1/(10 • 10 • 10) = 1/1,000 = 0.001.

How do I simplify a negative fraction?

To simplify a fractional negative exponent,you must first convert to a fraction.

  • If your starting base number is 16 − 1/2 {\\displaystyle 16^{-1/2}},start by converting it to a fraction where the exponent becomes positive when the base
  • 16 − 1/2 {\\displaystyle 16^{-1/2}} will become 1 16 1/2 {\\displaystyle {\\frac {1} {16^{1/2}}}}

    How do you solve for a negative exponent?

    Answer Wiki. A trick to solve negative exponent is to make a fraction. Put one on the top and put your base on the bottom. Your base should be to the power of the exponent except make sure to do it without the negative sign. Let’s try this with 2^-3. First, put one on the top and the base on the bottom.
