The Product Rule: a m × a n = a m + n The Quotient Rule: a m ÷ a n = a m - n The Power Rule: (a m) n = a mn Example: Simplify (3ab 4)(2a 2 b) 3 (x 2 y 4 /2xz) 3. Show Step-by-step Solutions General Rule. It worked for ½, it worked with ¼, in fact it works generally: x 1/n = The n-th Root of x. So we can come up with this:

You can rationalize the denominator by applying the following technique to a fraction of the form a b Indices maze · Indices eliminator · Basic laws of indices RAG · Fractional laws of indices RAG. ® PixiMaths 2017 Proudly created with Wix.com Uppingham, Choose whether you want to practice the operations on indices, the simplification of negative or fractional indices, or a mixture of these. Set a maximum power to 21 Nov 2016 Sometimes called powers or exponents, indices save writing out lots of multiples. See how to use two laws of indices for exponents with the

Fraction Rules. Below is a list of fraction basics as well as explanations for each rule. If the numerator remains the same for all fractions but the denominator gets larger, the actual value of the fraction gets smaller. This fraction rule is because of the fact that if the denominator increases then the whole is divided into more parts. Miller Indices Miller Indices Rules for Miller Indices: Determine the intercepts of the face along the crystallographic axes, in terms of unit cell dimensions. Take the reciprocals; Clear fractions; Reduce to lowest terms; For example, if the x-, y-, and z- intercepts are 2, 1, and 3, the Miller indices are calculated as: Take reciprocals: 1/2 Fraction Rules. Algebra rules for combining fractions. These rules apply for both proper fractions and improper fractions. They apply for all rational expressions as well. A. Special Fractions. 1. simplifies to b. 2. does not simplify any further. 3. simplifies to 0. 4. is undefined. Examples. 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 indices can be simplified using the laws of indices.

LAW 2: The second law of indices tells us that when dividing a number with an exponent by the same number with an exponent, we have to subtract the powers. In algebraic form, this rule is as follows . The a represents the number that is divided by itself and m and n represent the powers. Here is an example for this rule. Fraction Rules. Below is a list of fraction basics as well as explanations for each rule.

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.

Some numbers can be written in mathematical shorthand if the number is the product of "repeating numbers". eg 100 is the product of 10 multiplying itself two The 2 is called the index or power or exponent. 5 to the power of 2 = 5 × 5 = 25. INDEX RULES Fractional index, a(1/x) = xth root of a, 9(1/2) = √9 = 3. We use the laws of indices to simplify expressions involving indices. videos to review the use of indices including fractional indices, brackets and logarithms. Using negative indices produces fractions. The three rules at the start of section 3.2 can now be used for any integers m and n, not just for positive values.
