WebThe negative exponent means take the reciprocal, or flip the fraction, so, ( (-27)^-1/3) / 1 = 1 / ( (-27)^1/3), and the negative exponent is now a positive exponent. Regarding the fractional exponent, if the expression were telling you to cube, then the 3 would be in the numerator, but the 3 is in the denominator, so, you are supposed to take ... WebJan 30, 2024 · The index can be negative or fractional. In a fractional exponent, the exponent is always a fraction. Here, the numerator of the exponent is the power to …
WebExample 3: with a coefficient in front of base. Simplify and leave your answer in index form. 3b−2 3 b − 2. Notice how the index only affects the variable b. Put the term over 1. Show step. Flip and change the power -2 to +2. Show step. WebCalculating with Fractional Indices. For a fractional index, the numerator is a power term, and the denominator is a root term. 27 2 3 means square 27 then cube root the answer …
WebBut the problem in the video is 125^(1/2)/5^(1/2). These are not the same number. So, you need to use properties of exponents to convert to a common base. Or, as Sal shows in the video, we can rewrite the problem has one fraction raised to the common exponent. This then lets him reduce the fraction. Hope this helps.

WebLaws of indices methods. There are several laws of indices (sometimes called indices rules), including multiplying, dividing, power of 0, brackets, negative and fractional powers. For examples and practice questions on each of the rules of indices, as well as how to evaluate calculations with indices with different bases, follow the links below.
WebIL1.2 – Indices and Logarithms: Fractional Indices Page 3 of 3 June 2012 Exercises Exercise 1 Evaluate the following expressions. If the answer is not exact give the decimal approximation to two decimal places. (a) 1 642 (b) 1 1253 (c) 1 364 (d) 1. 81 2. − (e) 1. 128 7. − (f) 1. 2505. Exercise 2 create forge 1.19.2WebRaise the term inside the brackets by the power outside the brackets. (53)2 = 53 ×53 = 53+3 = 56 ( 5 3) 2 = 5 3 × 5 3 = 5 3 + 3 = 5 6. It is quicker to multiply the indices (powers) together. (53)2 = 53×2 = 56 ( 5 3) 2 = 5 3 × 2 = 5 6. 2 Make sure you have considered the coefficient.
