Webb26 juli 2012 · As I read this, the pronoun, "It," stands for the phrase "a number with a negative exponent." "A number with a negative exponent is the reciprocal of that number with a positive exponent." As long as a is not zero, then this is true. Look at the equation in the triple box above line ** . WebbThe negative sign on an exponent means the reciprocal. Think of it this way: just as a positive exponent means repeated multiplication by the base, a negative exponent …

WebbThe negative exponent tells us to re-write the expression by taking the reciprocal of the base and then changing the sign of the exponent. Any expression that has negative exponents is not considered to be in simplest form. We will use the definition of a negative exponent and other properties of exponents to write an expression with only ... WebbTo simplify a negative exponent, take the reciprocal of the term that is being raised by the exponent. Next, start simplifying by writing out all the exponents. For example, write 2x^3 as 2 x x x. Do this to every exponent. ... Negative exponent means whatever was in the top is going to be written in the bottom with the positive exponent. jennifer lawrence graham norton
Why are negative exponents reciprocals of the number?
WebbNegative Exponents In this tutorial, we will learn about negative exponents. When we change a negative exponent into positive exponent, we write the reciprocal of the given positive exponent. Negative sign means the reciprocal of the given number. For any non zero number a, (a-m = 1/am). Where m is a positive integer and a-m […] Webb4 feb. 2012 · To simplify expressions with integral exponents, you can use the following principle as well as the exponent laws. A power with a negative exponent can be written as a power with a positive exponent. • a-n = ___1 an,a ≠ 0 2 3 = _1 23 • _ 1 a-n n = a , a ≠ 0 _ 1 2-3 = 23 Example 1 Multiply or Divide Powers With the Same Base WebbDescription: The reciprocal of a fraction is the fraction turned on its head: the reciprocal of ``{2 \over 3}`` is ``{3 \over 2}``. We know from the previous rule that ``a^{-n}`` is the reciprocal of ``a^n``, so we can simply convert the fraction to its reciprocal by exchanging the numerator and denominator, and then the exponent becomes positive. pac 12 twitter basketball
