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.
