Fractional (rational) exponents are an alternate way to express radicals. Notice in the last example, that raising a square root to a power of 2 removes the Fractional exponents obey the same laws as do integral exponents. For example, Another way of expressing this would be Observe that the number 41/2 , when 20 May 2018 Series of slides, questions/examples/starters I have used recently on negative/ fractional indices. You might just want some questions for a bit of Simplifying fractional exponents. The base b raised to the power of n/m is equal to: bn/m = (m√b)n = m√(bn). Example: The base 2 raised to the power of 3/2 is Definition An index (plural: indices) is the power, or exponent, of a number. For example, \\( a^3 \\\) has an index of 3. A surd is an irrational number that can be 16 Feb 2006 This is seen to be consistent with the Power Rule for n = 2/3. Let's make a generalization of this example. Any rational number n can be In a fractional exponent, the numerator is the power to which the number should be taken and the denominator is the root which should be taken. For example

Fractional exponents are abbreviations for taking the roots of a number. For example, x½ means , the square root of x. This makes sense because, by the rules of

Introduction. The last area of power functions to be addressed is the case of a fractional exponent. In order to express a radical expression without a in fractional form, if you wish to calculate exponents such as 5 raised to the power of 5. To calculate radicals for example the square root of 144, enter 144 raised

Algebra uses symbols or letters to represent quantities; for example I = PRT to review the use of indices including fractional indices, brackets and logarithms.

You also need to understand what Fractional, Negative and Zero Indices are and how to work with them. Before you look at the following maths activities, make sure to already understand the 3 Laws of Indices (click here).The following example questions will explain to you what Fractional Indices are. Now if we’re going to try to make sense of negative and fractional exponents, then we must at least make sure that our definitions will stay consistent with these Laws of Exponents. For example, you may already know that the zero exponent on any base results in the number 1 (with one exception: 0 0 is undefined).

Indices revision for A-Level Maths. This section covers Indices and includes examples. Revise about how to multiply and divide indices, as well as apply negative and fractional rules of indices with this BBC Bitesize GCSE Maths Edexcel guide. Negative indices Example.

Fractional exponents obey the same laws as do integral exponents. For example, Another way of expressing this would be Observe that the number 41/2 , when

A fractional exponent is an alternate notation for expressing powers and roots together. For example, the following are equivalent.
