How to simplify indices
Did you know?
WebAn index number is a number which is raised to a power. The power, also known as the index, tells you how many times you have to multiply the number by itself. For example, 2 5 means that you have to multiply 2 by itself five times = 2×2×2×2×2 = 32. There are a number of important rules of index numbers: y a × y b = y a+b; Examples. 2 4 × ... WebMultiplying indices is where we multiply terms that involve indices or powers. There are two methods we can use to multiply terms involving indices. When the bases are the same E.g. a3 ×a4 = a3+4 =a7 a 3 × a 4 = a 3 + 4 = a 7 These questions usually ask you ‘simplify’ the calculation 2 When the bases are different E.g.
WebIndices provide a compact algebraic notation for repeated multiplication. For example, is it much easier to write 3 5 than 3 × 3 × 3 × 3 × 3. Once index notation is introduced the index laws arise naturally when simplifying numerical and algebraic expressions. Thus the simplificiation 2 5 × 2 3 = 2 8 quickly leads WebSimplifying expressions using the laws of indices Indices show where a number has been multiplied by itself, eg squared or cubed, or to show roots of numbers, eg square root. Some terms with... Simplifying expressions using the laws of indices Indices show where a number …
WebSimplifying Higher-Index Terms In the previous pages, we simplified square roots by taking out of the radical any factor which occurred in sets of two. For the second root, we needed a second copy. For higher-index roots, the thinking is the same. WebDividing indices Brackets with indices examples Example 1: single number base Write as a single power of 5: (53)2 ( 5 3) 2 Raise 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.
