## Working out negative fractional indices

How to evaluate powers that are negative unit fractions, like 9 raised to -½ and 27 raised to How do you work out a fraction to the power of a negative fraction? Jul 11, 2018 Exponents can be tricky. We'll review the laws of exponents and gain practice working out problems involving negative exponents and Nov 12, 2018 Once you've grasped that basic concept, you can start to add on extra layers like negative exponents, fractional exponents or even a 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. and so on. Journalism (CCEA) · Learning for Life and Work (CCEA) · Mandarin · Maths · Maths Numeracy (WJEC) · Media Studies · Modern Foreign Languages Exercises. 1. Write the following using only positive powers: (a). 1 x−6. , (b) x−12 A negative exponent just means that the base is on the wrong side of the fraction To fix this, I'll first convert the expression into a fraction in the way that any Unlike the previous exercise, the parentheses meant that the negative power did Negative Exponents. Exponents are also called Powers or Indices. Let us first look at what an "exponent" is: 8 to

## The exponent outside the parentheses. Multiplies the exponents inside. (an bm. ) -1. = bm an. Negative exponent ”flips” a fraction. b0 = 1 b = b1. Don't forget

Laws of indices. Indices are used to show numbers that have been multiplied by themselves. They can be used instead of the roots such as the square root. The rules make complex calculations that involve powers easier. Letters or numbers to the power of zero. Any letter or number to the power of zero is equal to 1. Fractional indices - Higher. An example of a fractional index is . The denominator of the fraction is the root of the number or letter, and the numerator of the fraction is the power to raise the answer to. By using multiplication rules it is clear to see that: Therefore: In general, , and so on. Negative Exponents. Exponents are also called Powers or Indices Let us first look at what an "exponent" is: The exponent of a number says how many times to use the number in a multiplication.

Series of slides, questions/examples/starters I have used recently on negative/fractional indices. You might just want some questions for a bit of practice.

Now we have a negative fractional exponent, and the key to this is to just not get too worried or intimidated by this, but just think about it step by step. Just ignore for the second that this is a fraction, and just look at this negative first. Just breathe slowly, and realize, OK, I got a negative exponent. Fractional and Negative Indices Instructions Use black ink or ball-point pen. Answer all questions. Answer the questions in the spaces provided — there may be more space than you need. Diagrams are NOT accurately drawn, unless otherwise indicated. You must show all your working out. Information The marks for each question are shown in brackets### This free exponent calculator determines the result of exponentiation, including of other calculators addressing math, finance, health, fitness, and more. While the rules for fractional exponents with negative bases are the same, they

Exponentiation is a mathematical operation, written as bn, involving two numbers , the base b Raising 0 to a negative exponent is undefined, but in some circumstances, On the other hand, exponentiation to a real power of a negative real number is The exponential function is defined for all integer, fractional, real , and
